CT-S851 Receipt Printer

The Citizen CT-S851 has reached end of life. It has been replaced by the Citizen CT-S851II.

The Citizen CT-S851 receipt printer gives you the power of an industry leading receipt printer with the familiarity of a consumer printer. An LCD display on the front on the printer provides easy-to-read status and menu controls, eliminating the hassle of digging through a manual to determine status updates. A nearly 12" per second print speed makes the CT-S851 one of the fastest on the market, keeping lines moving smoothly. Receipts feed from the front of the printer and so the CT-S851 can be stored under a desk with ease.

Citizen designed the CT-S851 for maximum uptime, installing an autocutter rated at 2 million cuts and thermal printhead rated 93.2 miles of printed receipts. Downtime from jammed cutters or dodgy printheads can be brutal, especially during peak hours. Choose the Citizen CT-S851 and avoid these issues altogether.

• Driver support for Windows XP, Vista, Java POS, OPOS, and CUPS
• Same footprint as Epson TM-T88 series receipt printers
• Speedy 11.8" per second print speed
• Paper near out sensor warns before roll runs out
