With the CT-S851, Citizen complements its family of powerful POS printers for cash desks, trade and gastronomy with a thermal printer including front output that produces receipts at 300 mm/sec. The self-explanatory operation and front output of receipts guarantee absolute security in the smallest space, in particular for surroundings where dirt, falling objects or spilled liquids are a daily occurrence. The integrated LCD display makes configuration easy even for beginners, while maintenance and exchange of consumables are optimised through coloured error messages.

The CT-S851 creates high quality receipts optionally in two colours at 8 dots/mm (203 dpi). It professionally prints text, graphics and 2D bar codes on paper widths of 83, 80, 60 and 58 mm as well as paper thicknesses between 65 and 150 µm. The integrated cutter separates receipts cleanly and virtually noiselessly, while the large selection of interfaces leaves nothing to be desired in terms of connection options.
