There are so many different kinds of printers. 3D printer is one of them. Nowadays 3D printer includes so many different types, such as 3D color printer, solid printer, 3D ink printer and so on. A printer can be defined as an output device for a computer, which prints results in the format of text or graphics. It produces a hard copy of documents stored in electronic form, generally on physical print media such as transparencies and papers. Generally for low volume of printing-in offices or for personal use; smaller printers like desktop printers are used. For bulk printing requirements however, the printing press is preferred. A desktop printer can be attached directly to a computer or can be directly connected to a network. It can normally print on a standard paper like A4 or letter size or sizes lesser than them.
Printers can be distinguished into two groups-Impact Printer and Non-Impact Printer. Impact printer creates text and images when tiny wire pins on print head strike the ink ribbon by physically contacting the paper. Impact printers include Dot matrix, Daisy- wheel and line printers.
Non-impact printer is a type of printer that generates text and graphics on paper without striking the paper. They are quieter in operation and can print finer, smoother and hi-resolution prints in lesser time.
The most commonly used types of printers are dot-matrix printers, inkjet printers and laser printers.
Inkjet Printers: One of the non-impact printers; it functions by spraying variable sizes of drops of ink on paper through the jets of ink. The cartridges have a series of tiny electrically heated chambers constructed by photolithography. The printers use aqueous inks based on a mixture of water, glycol and dyes or pigments. They are very easy to use, reasonably priced and easy to maintain. They produce high quality of color and black & white prints. The color cartridge has 3 different chambers for cyan, magenta and yellow color (C, M, Y) while the black cartridge has one chamber for black color (K).
Laser Printers: High quality of text and graphics are created by these printers. They are one of the most popular non-impact printers these days. There are various factors that determine the cost of this technology like the cost of paper, toner and the replacement cost of other consumables.
Varied range of cartridge components, ink or toner refills and other printer consumables which need replacement are offered by them.
