Line printers print an entire line of text at a time. Four principal designs exist.
The garage in Palo Alto where Hewlett and Packard began their company Hewlett-Packard logo used from to Bill Hewlett and David Packard graduated with degrees in electrical engineering from Stanford University in The Hp deskjet printer case study originated in a garage in nearby Palo Alto during a fellowship they had with a past professor, Frederick Terman at Stanford during the Great Depression.
Terman was considered a mentor to them in forming Hewlett-Packard. In Hewlett and Packard decided to formalize their partnership. Of the many projects they worked on, their very first financially successful product was a precision audio oscillatorthe Model HPA.
Their innovation was the use of a small incandescent light bulb known as a "pilot light" as a temperature dependent resistor in a critical portion of the circuit, the negative feedback loop which stabilized the amplitude of the output sinusoidal waveform.
The Model series of generators continued until at least as the AB, still tube-based but improved in design through the years.
They worked on counter-radar technology and artillery shell fuses during World War II, which allowed Packard but not Hewlett to be exempt from the draft. HP is recognized as the symbolic founder of Silicon Valleyalthough it did not actively investigate semiconductor devices until a few years after the " traitorous eight " had abandoned William Shockley to create Fairchild Semiconductor in Hewlett-Packard's HP Associates division, established arounddeveloped semiconductor devices primarily for internal use.
Instruments and calculators were some of the products using these devices. HP partnered in the s 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. The name was picked so that the HP logo "hp" could be turned upside down to be a reverse reflect image of the logo "dy" of the new company.
Eventually Dynac changed to Dymec, then was folded back into HP in These had a simple accumulator -based design, with registers arranged somewhat similarly to the Intel x86 architecture still used today. The series was produced for 20 years, in spite of several attempts to replace it, and was a forerunner of the HP and HP series of desktop and business computers.
The HP series of smart and intelligent terminals introduced forms-based interfaces to ASCII terminals, and also introduced screen labeled function keysnow commonly used on gas pumps and bank ATMs.
Although scoffed at in the formative days of computing, HP would eventually surpass even IBM as the world's largest technology vendor, in terms of sales. We therefore decided to call it a calculator, and all such nonsense disappeared.
The machine's keyboard was a cross between that of a scientific calculator and an adding machine. There was no alphabetic keyboard. Steve Wozniakco-founder of Appleoriginally designed the Apple I computer while working at HP and offered it to them under their right of first refusal to his work, but they did not take it up as the company wanted to stay in scientific, business, and industrial markets.
They introduced the world's first handheld scientific electronic calculator in the HPthe first handheld programmable in the HPthe first alphanumeric, programmable, expandable in the HP Cand the first symbolic and graphing calculator, the HPC.
Like their scientific and business calculators, their oscilloscopeslogic analyzersand other measurement instruments have a reputation for sturdiness and usability the latter products are now part of spin-off Agilent 's product line, which were later spun-off from Agilent as Keysight Technologies.
HP computers were similar in capabilities to the much later IBM Personal Computeralthough the limitations of available technology forced prices to be high. The print mechanisms in HP's tremendously popular LaserJet line of laser printers depend almost entirely on Canon Inc.
HP develops the hardware, firmware, and software that convert data into dots for the mechanism to print. HP also grew through acquisitions.
