Citizen CT-S310II Ethernet USB Thermal POS Receipt Printer

Connect a point-of-sale workstation or networked checkout environment to a direct-thermal receipt printer through wired Ethernet or USB. Citizen CT-S310IIETUBK combines both interfaces in a black desktop unit, allowing a local USB-connected terminal or an Ethernet-connected POS environment to use the same printer configuration. Direct-thermal operation produces receipts without ink or toner consumables, while the compact enclosure suits counter spaces where transaction printing must remain close to the operator. The CT-S310II prints at up to 160 mm/s and supports 203 dpi receipt output for readable transaction text, barcodes, and routine POS graphics. It accepts 80 mm paper as its standard receipt width and can also operate with 58 mm media. Drop-in paper loading reduces the time required to replace receipt rolls, and the integrated cutter separates completed receipts during busy checkout activity. Choose this interface and color variant when the installation requires both Ethernet and USB connectivity rather than a single-host-only connection. Ethernet supports placement on a wired local network, while USB provides a direct connection option for a nearby POS terminal. The black housing coordinates with dark POS peripherals and counter equipment. Its focused receipt-printing design fits retail lanes, hospitality service points, ticket counters, and other fixed-location transaction stations that require thermal paper output.
