Kiosk and POS Printers

Kiosk and POS printers are used with kiosks and point-of-sale (POS) systems such as electronic cash registers (ECR) and electronic funds transfer (EFT) devices. There are several basic printer technologies. Line printers contain a chain of characters or pins that print an entire line at time. They are very fast, but produce low-quality print. Dot matrix printers produce characters and illustrations by striking pins against an ink ribbon to print closely spaced dots in the appropriate shape. They can print multi-page forms, but are relatively slow compared to other types of kiosk and POS printers. Line matrix printers use the same technology as dot matrix printers, but are much faster and designed for greater workloads. Ink jet printers spray ink through a nozzle onto the page. Direct thermal printers use heat to set text and graphics on non-curling, smudge-proof paper. Thermal transfer printers use a combination of heat and pressure to transfer resin-based ink from tiny ribbons directly onto the paper. Laser printers use a laser beam to produce an image on a drum that is rolled through a reservoir of toner. The charged portions of the drum pick up the toner and transfer it to the paper through a combination of heat and pressure. LCD and LED printers are similar to laser printers, but use liquid crystal displays (LCD) and light emitting diodes (LEDs), respectively.
