Product Description
The Citizen CT-E351, part number CT-E351RSU-BK, is a compact 3-inch direct thermal POS receipt printer with front paper exit. This version has dual USB and RS-232 serial interfaces and a black case. Citizen lists hospitality, retail, ticketing and queue management among the CT-E351's applications and describes it as fitting small spaces.

- Print performance: up to 250 mm/sec at 203 dpi, with a print width of up to 72 mm.
- Guillotine cutter: full or partial cut.
- Cash drawer control: RJ12 drawer kick-out connector that supports two cash drawers.
- Drip resistance: Citizen states the CT-E351 complies with IPX1 for vertically falling water drops, while noting it is not guaranteed to be completely drip-proof.

How it compares
Citizen builds the CT-E351 with two interface options, RS (USB + serial) and ET (Ethernet + USB), and in black (BK) or pure white (WH). Choose an ET version if your POS software prints to a network printer. Citizen's CT-E301 is a related model with top paper exit rather than the CT-E351's front exit.
