Printers

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper. Usually to standard-size, 8.5″ by 11″ sheets of paper. It vary in size, speed, sophistication and cost.

Early impact worked something like an automatic typewriter, with a key striking an inked impression on paper for each printed character. The dot matrix, an impact that strikes the paper a line at a time, was a popular low-cost option.

The best-known non-impact are the inkjet and the laser. The inkjet sprays ink from an ink cartridge at very close range to the paper as it rolls by. While the laser uses a laser beam reflected from a mirror to attract ink (called toner) to selected paper areas as a sheet rolls over a drum. Moreover,. So,. Therefore,.

Different types

There are many different manufacturers available today, including Canon, Epson, Hewlett-Packard, Xerox and Lexmark, among many others. There are also several types to choose from. Which we’ll explore below.

• Inkjet recreate a digital image by spraying ink onto paper. These are the most common type of personal printer.
• Laser
• 3D are a relatively new printer technology. 3D printing creates a physical object from a digital file. It works by adding layer upon layer of material until the print job is complete and the object is whole.
• Thermal produce an image on paper by passing paper with a thermochromic coating over a print head comprised of electrically heated elements and produces an image in the area where the heated coating turns black. A dye-sublimation printer is a form of thermal printing technology that uses heat to transfer dye onto materials.
• All-in-one are multifunction devices that combine printing with other technologies such as a copier, scanner and/or fax machine.
• LED are similar to laser printers but use a light-emitting diode array in the print head instead of a laser.
• Photo are similar to inkjet printers but are designed specifically to print high-quality photos, which require a lot of ink and special paper to ensure the ink doesn’t smear.
