Compact POS printer for retail counters

The Citizen CT-S310IIETUBK is a line thermal dot printer built for point-of-sale stations that need fast receipt and barcode output. It accepts 80 mm and 58 mm paper rolls up to 83 mm diameter and prints at 160 mm per second. Ethernet and USB interfaces connect directly to LAN or host systems. The guillotine cutter supports full or partial cuts by software command.

Low idle draw and quiet standby

Printing power draw is 32 watts while sleep mode consumes .6 watt and USB power-save drops to .18 watt. The Energy Star approved supply operates on AC 100 to 240 volts at 47 to 63 Hz. Thermal line printing keeps acoustic output low during normal counter use. The halogen-free housing and recycled packaging meet the stated environmental targets.

203 dpi resolution for standard barcodes

The print head delivers 8 dots per mm (203 dpi) across a maximum 72 mm width. Supported symbologies include UPC-A/E, EAN 13/8, ITF, CODE39, CODE128, CODABAR, CODE93, PDF417, QR Code and GS1-DataBar. Font A, B and C column counts scale with paper width. The head is rated for 300 million pulses or 150 km, extendable to 200 km with the long-life print function.

Questions about this item

How do I connect the CT-S310IIETUBK to my network and which step is often missed?

Plug the Ethernet cable into the LAN port and the USB cable if needed, then run the driver installer so the OS assigns a static IP instead of relying on DHCP alone.

Which part will need replacement first and how is it serviced?

The guillotine cutter is rated for high volume; when it dulls, open the top cover, release the cutter latch, and swap in a new cutter module without tools.

What limit appears first during continuous high-speed printing?

The thermal head reaches its 150 km MCBF threshold before the 300 million pulse rating, so plan a head swap around that distance.
