POS Hardware – Overview of Receipt Printer

At this blog, we will briefly introduce overview of receipt printer. Receipt printer is an output device connected to computer that print information from the POS system. There are two type of connection either parallel or USB port. Generally for POS system they either use thermal receipt printer or dot matrix receipt printer.

Thermal Receipt Printer

A thermal printer (or direct thermal printer) produces a printed image by selectively heating coated thermo chromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head.

Thermal printers print faster than dot matrix printers. Even though the paper is more expensive, printers can be rapidly refilled, leading to almost zero downtime. It doesn't require a ribbon. 

Dot Matrix Receipt Printer

Dot matrix printer is a type of computer printer with a print head that runs 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, much like a typewriter.

Dot matrix printers can make carbon-copies however normally it is noisy and can only print low resolution graphics, with limited color performance, limited quality and low speed.
