Citizen CT-E351RSU-BK Thermal POS Printer

Overview

The Citizen CT-E351RSU-BK is a compact thermal receipt printer engineered for point-of-sale and light-duty transaction printing in retail, hospitality, and small food-service environments. Front-exit paper path means tickets feed forward out of the device — a critical detail if your counter space is tight or you need receipts within arm's reach without reaching around the printer. USB and serial connectivity options give you flexibility whether you're replacing legacy hardware on a serial terminal or integrating into a modern USB-based POS system without additional adapters.

Compatibility

The CT-E351RSU-BK works with any POS software that supports standard thermal receipt printers via USB device class (HID/Mass Storage) or RS-232 serial (9-pin D-sub). No proprietary drivers required for many legacy systems. Confirms compatibility with older DOS-based and Windows XP/7 retail environments; verify serial port availability on newer terminals, as USB is the more common integration path on current hardware.

Installation Notes

Mount on counter or under-counter using the integrated stand or optional VESA bracket. Ensure at least 6 inches of clearance in front of the unit for paper loading and jam clearing. USB port requires standard 5V power supply (included); serial installation uses a shielded DB-9 cable (not included — source separately). Paper width: standard 80mm thermal stock. Test paper feed after installation — front-exit mechanics can jam if media is not cut straight or loaded backwards.
