National Register of Historic Places
–
The National Register of Historic Places is the United States federal governments official list of districts, sites, buildings, structures, and objects deemed worthy of preservation. The passage of the National Historic Preservation Act in 1966 established the National Register, of the more than one million properties on the National Register,80,000 are listed individually. The remainder are contributing resources within historic districts, each year approximately 30,000 properties are added to the National Register as part of districts or by individual listings. For most of its history the National Register has been administered by the National Park Service and its goals are to help property owners and interest groups, such as the National Trust for Historic Preservation, coordinate, identify, and protect historic sites in the United States. While National Register listings are mostly symbolic, their recognition of significance provides some financial incentive to owners of listed properties, protection of the property is not guaranteed. During the nomination process, the property is evaluated in terms of the four criteria for inclusion on the National Register of Historic Places, the application of those criteria has been the subject of criticism by academics of history and preservation, as well as the public and politicians. Occasionally, historic sites outside the proper, but associated with the United States are also listed. Properties can be nominated in a variety of forms, including individual properties, historic districts, the Register categorizes general listings into one of five types of properties, district, site, structure, building, or object. National Register Historic Districts are defined geographical areas consisting of contributing and non-contributing properties, some properties are added automatically to the National Register when they become administered by the National Park Service. These include National Historic Landmarks, National Historic Sites, National Historical Parks, National Military Parks/Battlefields, National Memorials, on October 15,1966, the Historic Preservation Act created the National Register of Historic Places and the corresponding State Historic Preservation Offices. Initially, the National Register consisted of the National Historic Landmarks designated before the Registers creation, approval of the act, which was amended in 1980 and 1992, represented the first time the United States had a broad-based historic preservation policy. To administer the newly created National Register of Historic Places, the National Park Service of the U. S. Department of the Interior, hartzog, Jr. established an administrative division named the Office of Archeology and Historic Preservation. Hartzog charged OAHP with creating the National Register program mandated by the 1966 law, ernest Connally was the Offices first director. Within OAHP new divisions were created to deal with the National Register, the first official Keeper of the Register was William J. Murtagh, an architectural historian. During the Registers earliest years in the late 1960s and early 1970s, organization was lax and SHPOs were small, understaffed, and underfunded. A few years later in 1979, the NPS history programs affiliated with both the U. S. National Parks system and the National Register were categorized formally into two Assistant Directorates. Established were the Assistant Directorate for Archeology and Historic Preservation and the Assistant Directorate for Park Historic Preservation, from 1978 until 1981, the main agency for the National Register was the Heritage Conservation and Recreation Service of the United States Department of the Interior. In February 1983, the two assistant directorates were merged to promote efficiency and recognize the interdependency of their programs, jerry L. Rogers was selected to direct this newly merged associate directorate

Palo Alto, California
–
Palo Alto is a charter city located in the northwest corner of Santa Clara County, California, in the San Francisco Bay Area of the United States. The city shares its borders with East Palo Alto, Mountain View, Los Altos, Los Altos Hills, Stanford, Portola Valley and it is named after a coast redwood tree called El Palo Alto. Palo Alto was established by Leland Stanford Sr. when he founded Stanford University, following the death of his son and it has also served as an incubator to several other high-technology companies such as Google, Facebook, Logitech, Intuit, Pinterest, and PayPal. As of the 2010 census, the total resident population is 64,403. Palo Alto is one of the most expensive cities in the United States, the recorded history of Palo Alto dates back to 1769, when Gaspar de Portolá noted an Ohlone settlement. This remains an area of known Indian mounds, a plaque at Middlefield Road and Embarcadero Road commemorates the area. The city got its name from a tall coast redwood tree, named El Palo Alto, a plaque there recounts the story of the Portolà expedition, a 63-man, 200-horse expedition from San Diego to Monterey from November 7–11,1769. The group overshot Monterey in the fog and when they reached modern-day Pacifica, they ascended Sweeney Ridge, thinking the bay was too wide to cross, the group retraced their journey to Monterey, never becoming aware of the Golden Gate entrance to the Bay. Located south of the San Francisquito Creek, west of todays I-280, in 1835, Rafael Soto and family settled near the San Francisquito Creek near Newell and Middlefield, selling goods to travelers. Rafael Soto died in 1839, but his wife, Maria Antonia Mesa, was granted Rancho Rinconada del Arroyo de San Francisquito in 1841, in 1839, their daughter María Luisa Soto married John Coppinger, who was the grantee of Rancho Cañada de Raymundo. Rancho Cañada de Raymundo was West of San Francisquito Creek, and began at Alambique Creek, the border of Rancho Corte de Madera. Bear Gulch Creek flowed on his land in Portola Valley, the rancho also abutted Buelnas grant near Skyline Boulevard and Matadero Creek. Upon Coppingers death, Maria inherited it and later married a visiting boat captain, Greer owned a home on the site that is now Town & Country Village on Embarcadero and El Camino Real. Greer Avenue and Court are named for him, to the west of Rafael Soto, near El Camino and following the Creek, was Rancho San Francisquito granted in 1839 to Antonio Buelna and wife Maria Concepcion. To the south of the Sotos, the brothers Secundino and Teodoro Robles in 1849 bought Rancho Rincon de San Francisquito from José Peña, where the Joness house was, then east down Arastradero Rd. to the north property line of Alta Mesa Memorial Park and Terman Park. The property then went along the bay to the Embarcadero, a boundary in the day, then up to the Stanford University gates, up Galvez. The grant was bounded on the south by Mariano Castros Rancho Pastoria de las Borregas grant across San Antonio Road, thats the Robles Rancho, about 80% of Palo Alto and Stanford University. It was whittled down by 1863 through courts to 6,981 acres, stories say their grand hacienda was built on the former meager adobe of José Peña near Ferne off San Antonio Road, midway between Middlefield and Alma Street

Museum
–
Most large museums are located in major cities throughout the world and more local ones exist in smaller cities, towns and even the countryside. Museums have varying aims, ranging from serving researchers and specialists to serving the general public, the goal of serving researchers is increasingly shifting to serving the general public. There are many types of museums, including art museums, natural history museums, science museums, war museums, the city with the largest number of museums is Mexico City with over 128 museums. According to The World Museum Community, there are more than 55,000 museums in 202 countries, the English museum comes from the Latin word, and is pluralized as museums. The first museum/library is considered to be the one of Plato in Athens, however, Pausanias gives another place called Museum, namely a small hill in Classical Athens opposite to the Akropolis. The hill was called Mouseion after Mousaious, a man who used to sing on the hill, the purpose of modern museums is to collect, preserve, interpret, and display items of artistic, cultural, or scientific significance for the education of the public. The purpose can also depend on ones point of view, to a family looking for entertainment on a Sunday afternoon, a trip to a local history museum or large city art museum could be a fun, and enlightening way to spend the day. To city leaders, a healthy museum community can be seen as a gauge of the health of a city. To a museum professional, a museum might be seen as a way to educate the public about the museums mission, Museums are, above all, storehouses of knowledge. In 1829, James Smithsons bequest, that would fund the Smithsonian Institution, stated he wanted to establish an institution for the increase, Museums of natural history in the late 19th century exemplified the Victorian desire for consumption and for order. Gathering all examples of classification of a field of knowledge for research. As American colleges grew in the 19th century, they developed their own natural history collections for the use of their students, while many large museums, such as the Smithsonian Institution, are still respected as research centers, research is no longer a main purpose of most museums. While there is a debate about the purposes of interpretation of a museums collection, there has been a consistent mission to protect. Much care, expertise, and expense is invested in efforts to retard decomposition in aging documents, artifacts, artworks. All museums display objects that are important to a culture, as historian Steven Conn writes, To see the thing itself, with ones own eyes and in a public place, surrounded by other people having some version of the same experience can be enchanting. Museum purposes vary from institution to institution, some favor education over conservation, or vice versa. For example, in the 1970s, the Canada Science and Technology Museum favored education over preservation of their objects and they displayed objects as well as their functions. One exhibit featured a printing press that a staff member used for visitors to create museum memorabilia

Hewlett-Packard
–
The Hewlett-Packard Company or shortened to Hewlett-Packard was an American multinational information technology company headquartered in Palo Alto, California. The company was founded in a garage in Palo Alto by William Bill Redington Hewlett and David Dave Packard. HP was the worlds leading PC manufacturer from 2007 to Q22013 and it specialized in developing and manufacturing computing, data storage, and networking hardware, designing software and delivering services. HP also had services and consulting business around its products and partner products.4 billion in 2008, in November 2009, HP announced the acquisition of 3Com, with the deal closing on April 12,2010. On April 28,2010, HP announced the buyout of Palm, on September 2,2010, HP won its bidding war for 3PAR with a $33 a share offer, which Dell declined to match. On October 6,2014, Hewlett-Packard announced plans to split the PC and printers business from its enterprise products, the split closed on November 1,2015, and resulted in two publicly traded companies, HP Inc. and Hewlett Packard Enterprise. William Redington Hewlett and David Packard graduated with degrees in engineering from Stanford University in 1935. The company originated in a garage in nearby Palo Alto during a fellowship they had with a past professor, Terman was considered a mentor to them in forming Hewlett-Packard. In 1939, Packard and Hewlett established Hewlett-Packard in Packards garage with a capital investment of US$538. Hewlett and Packard tossed a coin to decide whether the company they founded would be called Hewlett-Packard or Packard-Hewlett, HP incorporated on August 18,1947, and went public on November 6,1957. Of the many projects they worked on, their very first financially successful product was an audio oscillator. This allowed them to sell the Model 200A for $54.40 when competitors were selling less stable oscillators for over $200, the Model 200 series of generators continued until at least 1972 as the 200AB, still tube-based but improved in design through the years. They worked on technology and artillery shell fuses during World War II. Hewlett-Packards HP Associates division, established around 1960, developed semiconductor devices primarily for internal use, instruments and calculators were some of the products using these devices. HP partnered in the 1960s with Sony and the Yokogawa Electric companies in Japan to develop several high-quality products, the products were not a huge success, as there were high costs in building HP-looking products in Japan. HP and Yokogawa formed a joint venture in 1963 to market HP products in Japan, HP bought Yokogawa Electrics share of Hewlett-Packard Japan in 1999. HP spun off a company, Dynac, to specialize in digital equipment. The name was picked so that the HP logo hp could be turned upside down to be a reverse image of the logo dy of the new company

Silicon Valley
–
Silicon Valley is a nickname for the southern portion of the San Francisco Bay Area, in the northern part of the U. S. state of California. The valley in its name refers to the Santa Clara Valley in Santa Clara County, which includes the city of San Jose and surrounding cities and towns, where the region has been traditionally centered. The region has expanded to include the half of the San Francisco Peninsula in San Mateo County. It was in the Valley that the integrated circuit, the microprocessor. As of 2013, the region employed about a quarter of an information technology workers. The term is now used as a synecdoche for the American high-technology economic sector. The first published use of Silicon Valley is credited to Don Hoefler, hostler used the phrase as the title of a series of articles in the weekly trade newspaper Electronic News. The series, entitled Silicon Valley in the USA, began in the papers January 11,1971, the term gained widespread use in the early 1980s, at the time of the introduction of the IBM PC and numerous related hardware and software products to the consumer market. The silicon part of the name refers to the concentration of companies involved in the making of semiconductors. These firms slowly replaced the orchards and the fruits which gave the area its initial nickname — the Valley of Hearts Delight, Stanford University leadership was especially important in the valleys early development. Together these elements formed the basis of its growth and success, the ship had been outfitted with a wireless telegraph transmitter by a local newspaper, so that they could prepare a celebration on the return of the American sailors. Local historian Clyde Arbuckle states in Clyde Arbuckles History of San Jose that California first heard the click of a key on September 11,1853. It marked completion of an enterprise begun by a couple of San Francisco Merchants Exchange members named George Sweeney and it was known as the Inner Station, the second, as the Outer Station. Both used their primitive mode of communication until Messrs, Sweeney and Baugh connected the Outer Station directly with the Merchantss Exchange by electric telegraph Wire. According to Arbuckle Sweeney and Baughs line was strictly an intra-city, San Francisco-based service, allen and C. Burnham led the way to build a line from San Francisco to Marysville via San Jose, Stockton, and Sacramento. Delays to construction occurred until September 1853, but, …San Jose became the first station on the line when the wire arrived here on October 15, the line was completed when Gambles northbound crew met a similar crew working southward from Marysville on October 24. The Bay Area had long been a site of United States Navy research. In 1909, Charles Herrold started the first radio station in the United States with regularly scheduled programming in San Jose

Stanford University, officially Leland Stanford Junior University, is a private research university in Stanford, California, adjacent to Palo Alto and between San Jose and San Francisco. Its 8, 180-acre campus is one of the largest in the United States, Stanford also has land and facilities elsewhere. The university was founded in 1885 by Leland and Jane Stanford in memory of their only child, Stanford was a former Governor of California and U. S. Senator, he made his fortune as a railroad tycoon. The school admitted its first students 125 years ago on October 1,1891, Stanford University struggled financially after Leland Stanfords death in 1893 and again after much of the campus was damaged by the 1906 San Francisco earthquake. Following World War II, Provost Frederick Terman supported faculty and graduates entrepreneurialism to build self-sufficient local industry in what would later be known as Silicon Valley. The university is one of the top fundraising institutions in the country. There are three schools that have both undergraduate and graduate students and another four professional schools. Students compete in 36 varsity sports, and the university is one of two institutions in the Division I FBS Pac-12 Conference. Stanford faculty and alumni have founded a number of companies that produce more than $2.7 trillion in annual revenue. It is the alma mater of 30 living billionaires,17 astronauts and it is also one of the leading producers of members of the United States Congress. Sixty Nobel laureates and seven Fields Medalists have been affiliated with Stanford as students, alumni, Stanford University was founded in 1885 by Leland and Jane Stanford, dedicated to Leland Stanford Jr, their only child. The institution opened in 1891 on Stanfords previous Palo Alto farm, despite being impacted by earthquakes in both 1906 and 1989, the campus was rebuilt each time. In 1919, The Hoover Institution on War, Revolution and Peace was started by Herbert Hoover to preserve artifacts related to World War I, the Stanford Medical Center, completed in 1959, is a teaching hospital with over 800 beds. The SLAC National Accelerator Laboratory, which was established in 1962, in 2008, 60% of this land remained undeveloped. Besides the central campus described below, the university also operates at more remote locations, some elsewhere on the main campus. Stanfords main campus includes a place within unincorporated Santa Clara County. The campus also includes land in unincorporated San Mateo County, as well as in the city limits of Menlo Park, Woodside. The academic central campus is adjacent to Palo Alto, bounded by El Camino Real, Stanford Avenue, Junipero Serra Boulevard, the United States Postal Service has assigned it two ZIP codes,94305 for campus mail and 94309 for P. O. box mail

Walt Disney Studios (Burbank)
–
The Walt Disney Studios, in Burbank, California, United States, serves as the corporate headquarters for The Walt Disney Company media conglomerate. The Studios are one of two major studios that do not currently offer backlot tours to the general public, the other being 20th Century Fox. For several years, Adventures by Disney has offered tours of the studio, the other way to tour the studio is to join the official Disney D23 fan club, which offers tours to members every few months. The studio used to open to the once a year in November on the Saturday before Thanksgiving for its annual Magical Holiday Faire craft sale. As an aid to visitors, many buildings on the Disney lot are marked with identifying signs that include historical information. The Studio is a part of the Walt Disney Studios Disney Studio Services unit – along with Golden Oak Ranch, The Prospect Studios, prior to the official opening of the Burbank lot in 1940, the Walt Disney Studios was situated at several different locations in Los Angeles. During summer 1923, Walt Disney created The Disney Bros, cartoon Studio in his uncle Robert Disneys garage, which was located at 4406 Kingswell Avenue, in the Los Feliz neighborhood of Los Angeles. This garage has been on display at the Stanley Ranch Museum in Garden Grove since the 1980s and his brother Roy O. Disney was also in Los Angeles at the time. During October 1923, the brothers leased office space on the side of a real estate agencys office at 4651 Kingswell Avenue. On October 16,1923, Walt Disney accepted an offer from Margaret Winkler of Universal Studios to distribute the new Alice Comedies starring Virginia Davis. It was also at this site where on January 14,1924, Walt Disney met his future wife Lillian Bounds, in February 1924, the studio moved next door to an office of its own at 4649 Kingswell Avenue. The late Robert Disneys residence and the office building that is home to 4649 and 4651 Kingswell Avenue have survived to the present and are still in use. In 1925, Walt Disney placed a deposit on a new, considerably larger lot at 2719 Hyperion Avenue, and it was here where, after a train journey with his wife Lillian, Walt fully created the character of Mickey Mouse in 1928. The first color animated film, the Silly Symphony Flowers and Trees, in 1937, the Hyperion studio produced the worlds first full-length animated feature film, Snow White and the Seven Dwarfs. Disneys staff began to grow to a size at the Hyperion studio. The current Walt Disney Studios, located at 500 South Buena Vista Street, Burbank, was possible by the revenue from the 1937 release of Snow White. Walt Disney and his staff began the move from the old studio at Hyperion Avenue in Silver Lake on December 24,1939, a bungalow and other small buildings that were located at the Hyperion Avenue location were moved to Burbank. Disney purposely planned his new Burbank studio around the animation process, underground tunnels linked some of the buildings, and the lot also included a movie theatre, a sound stage, and a commissary

Stereophonic sound
–
Stereophonic sound or, more commonly, stereo, is a method of sound reproduction that creates an illusion of multi-directional audible perspective. Thus the term applies to so-called quadraphonic and surround-sound systems as well as the more common two-channel. It is often contrasted with monophonic, or mono sound, where audio is heard as coming from one position, in the 2000s, stereo sound is common in entertainment systems such as broadcast radio and TV, recorded music and the cinema. The word stereophonic derives from the Greek στερεός, firm, solid + φωνή, sound, tone, voice and it was coined in 1927 by Western Electric, the signal is then reproduced over multiple loudspeakers to recreate, as closely as possible, the live sound. Secondly artificial or pan-pot stereo, in which a sound is reproduced over multiple loudspeakers. By varying the amplitude of the signal sent to each speaker an artificial direction can be suggested. The control which is used to vary this relative amplitude of the signal is known as a pan-pot, by combining multiple pan-potted mono signals together, a complete, yet entirely artificial, sound field can be created. In technical usage, true stereo sound recording and sound reproduction that uses stereographic projection to encode the relative positions of objects and events recorded. During two-channel stereo recording, two microphones are placed in strategically chosen locations relative to the source, with both recording simultaneously. The two recorded channels will be similar, but each will have distinct time-of-arrival and sound-pressure-level information, during playback, the listeners brain uses those subtle differences in timing and sound level to triangulate the positions of the recorded objects. Stereo recordings often cannot be played on systems without a significant loss of fidelity. This phenomenon is known as phase cancellation and this two-channel telephonic process was commercialized in France from 1890 to 1932 as the Théâtrophone, and in England from 1895 to 1925 as the Electrophone. Both were services available by coin-operated receivers at hotels and cafés, modern stereophonic technology was invented in the 1930s by British engineer Alan Blumlein at EMI, who patented stereo records, stereo films, and also surround sound. In early 1931, Blumlein and his wife were at a local cinema, Blumlein declared to his wife that he had found a way to make the sound follow the actor across the screen. The genesis of ideas is uncertain, but he explained them to Isaac Shoenberg in the late summer of 1931. His earliest notes on the subject are dated 25 September 1931, the application was dated 14 December 1931, and was accepted on 14 June 1933 as UK patent number 394,325. The patent covered many ideas in stereo, some of which are used today and these discs used the two walls of the groove at right angles in order to carry the two channels. Much of the development work on this system for cinematic use did not reach completion until 1935, in Blumleins short test films, his original intent of having the sound follow the actor was fully realised

Fantasia (1940 film)
–
Fantasia is a 1940 American animated film produced by Walt Disney and released by Walt Disney Productions. With story direction by Joe Grant and Dick Huemer, and production supervision by Ben Sharpsteen, the film consists of eight animated segments set to pieces of classical music conducted by Leopold Stokowski, seven of which are performed by the Philadelphia Orchestra. Music critic and composer Deems Taylor acts as the films Master of Ceremonies, as production costs grew higher than what it could earn, Disney decided to include the short in a feature-length film with other segments set to classical pieces. Fantasia was first released in theatrical roadshow engagements held in thirteen U. S. cities from November 13,1940, the film was subsequently reissued multiple times with its original footage and audio being deleted, modified, or restored in each version. As of 2012, Fantasia has grossed $76.4 million in revenue and is the 22nd highest-grossing film of all time in the U. S. when adjusted for inflation. Fantasia, as a franchise, has grown to include games, Disneyland attractions, a live concert. Fantasia opens with live action scenes of members of an orchestra gathering against a background and tuning their instruments in half-light. Master of ceremonies Deems Taylor enters the stage and introduces the program, Toccata and Fugue in D Minor by Johann Sebastian Bach. Live-action shots of the orchestra illuminated in blue and gold, backed by superimposed shadows, animated lines, shapes and cloud formations reflect the sound and rhythms of the music. Nutcracker Suite by Pyotr Ilyich Tchaikovsky, selections from the ballet suite underscore scenes depicting the changing of the seasons from summer to autumn to winter. The Sorcerers Apprentice by Paul Dukas, based on Goethes 1797 poem Der Zauberlehrling. Mickey Mouse, the apprentice of the sorcerer Yen Sid, attempts some of his masters magic tricks. Rite of Spring by Igor Stravinsky, a visual history of the Earths beginnings is depicted to selected sections of the ballet score. The sequence progresses from the formation to the first living creatures, followed by the reign. Intermission/Meet the Soundtrack, The orchestra musicians depart and the Fantasia title card is revealed, after the intermission there is a brief jam session of jazz music led by a clarinettist as the orchestra members return. Then a humorously stylized demonstration of how sound is rendered on film is shown, an animated sound track character, initially a straight white line, changes into different shapes and colors based on the sounds played. The Pastoral Symphony by Ludwig van Beethoven, a mythical Greco-Roman world of colorful centaurs and centaurettes, cupids, fauns and other figures from classical mythology is portrayed to Beethovens music. A gathering for a festival to honor Bacchus, the god of wine, is interrupted by Zeus, Dance of the Hours by Amilcare Ponchielli

National Park Service
–
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational, inspirational, and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS. On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until later that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and then National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States. In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was later returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service

HP LaserJet
–
LaserJet as a brand name identifies the line of dry electrophotographic laser printers marketed by the American computer company Hewlett-Packard. The HP LaserJet was the worlds first desktop laser printer, as of 2016, Canon supplies both mechanisms and cartridges for all HPs laser printers. HP LaserJet printers employ xerographic laser-marking engines sourced from the Japanese company Canon, due to a very tight turnaround schedule on the first HP LaserJet, HP elected to use the controller already developed by Canon for the CX engine in the first HP LaserJet. The first HP LaserJet and the first Apple LaserWriter used the print engine. HP chose to use their in-house developed Printer Command Language as opposed to Apple, the use of a less-ambitious and simpler Page Description Language allowed HP to deliver its LaserJet to the market about a year before Apples CX based product, and for $1000 less. The sharing of an identical Canon engine in two competing products continued with the HP LaserJet II/III and the Apple LaserWriter II, which used the Canon LBP-SX print engine. HP introduced the first laser printer for IBM compatible personal computers in May 1984 at the Computer Dealers Exhibition, due to the high cost of memory, the first LaserJet only had 128 kilobytes of memory, and a portion of that was reserved for use by the controller. The HP LaserJet printer had high print quality, could print horizontally or vertically and it was ideal for printing memos, letters, and spreadsheets. It was quiet compared to other printers, so people could talk on the phone while sitting next to the HP LaserJet printer as it was printing. The first LaserJet was a replacement for text-only daisy wheel impact printers. By using control codes it was possible to change the printed text style using font patterns stored in permanent ROM in the printer. Although unsupported by HP, because the Laserjet used the same basic PCL language spoken by HPs other printers it was possible to use the Laserjet on HP3000 multiuser systems, the LaserJet Plus followed in September 1985, priced at US$3,995. It introduced soft fonts, treatments like bold and italic and other features including a parallel interface and it also included 512 kilobytes of memory, which was just enough to print graphics at 300 dpi that covered about 70% of the letter-size page area. In March 1986 HP introduced the LaserJet D+, which included the LaserJet print engine and formatter, in 1986, desktop publishing came to the world of IBM PCs and compatibles, after its origin on the Apple Macintosh and Apple LaserWriter. HP introduced the laser printer, the LaserJet series II. The HP LaserJet II was designed from the ground up as a printer with correct order page output as opposed to being leveraged from the Canon PC-20 personal copier. The HP LaserJet II used PCL4, improved features, more memory, also in March 1987, the LaserJet 2000 was launched. A high-end, networkable printer, the LaserJet 2000 offered a duty cycle of 70,000 pages per month, the HP LaserJet IID was released in the fall of 1988, It was the first desktop laser printer capable of duplexing
