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]
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]
In computer networking, a print server, or printer server, is a type of server that connects printers to client computers over a network. [1] It accepts print jobs from the computers and sends the jobs to the appropriate printers, queuing the jobs locally to accommodate the fact that work may arrive more quickly than the printer can actually handle.
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]

Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor [1] at Diablo Data Systems.It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster.
On older personal computer motherboards, the southbridge is one of the two chips in the core logic chipset, handling many of a computer's input/output functions. The other component of the chipset is the northbridge, which generally handles high speed onboard communications.
