The print engine of most All-in-one devices is based either on a home desktop inkjet printer, or on a home desktop laser printer. They may be black-and-white or colour capable. Laser models provide a better result for text while inkjet gives a more convincing result for images and they are a cheaper multifunctional. [3]
The band printer is a later variant where the characters are embossed on a flexible steel band. The LP27 from Digital Equipment Corporation is a band printer. Bar printers, where the character set is attached to a solid bar that moves horizontally along the print line, such as the IBM 1443. [21]
A computer printer is a computer peripheral device that produces a hard copy (permanent human-readable text and/or graphics usually on paper) from data stored in a computer connected to it. A virtual printer is a piece of computer software whose user interface and API resemble that of a printer driver, but which is not connected with a physical ...
The laser printer was invented at Xerox PARC in the 1970s. Laser printers were introduced for the office and then home markets in subsequent years by IBM, Canon, Xerox, Apple, Hewlett-Packard and many others. Over the decades, quality and speed have increased as prices have decreased, and the once cutting-edge printing devices are now ubiquitous.
Inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. [1] Inkjet printers were the most commonly used type of printer in 2008, [2] [needs update] and range from small inexpensive consumer models to expensive professional machines.
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
It was a compact monotonic printer with a resolution of 240 dpi and a speed of 16 ppm. A 1989 model called OL400 was noted for its low cost. By 1997, Oki has pushed the resolution to 1200 dpi, and has produced upscaled models that handle A3-sized paper. The OKIPAGE 8c from 1998 was the first color LED printer for OKI.
Dot matrix printers are a type of impact printer that prints using a fixed number of pins or wires [2] [3] and typically use a print head that moves back and forth or in an up-and-down motion on the page and prints by impact, striking an ink-soaked cloth ribbon against the paper. They were also known as serial dot matrix printers. [4]
