Singular Expert Insight
Choose the CT-S310II if you need a proven, low-cost 80 mm thermal POS printer with both USB and Serial connectivity for a fixed counter. If you specifically need Ethernet/LAN printing for a back-office or networked kitchen, consider the Citizen CT-S751II / CT-S651II with built-in network options instead.

Buyer's Guide

Buy it if
You run a retail till, café / restaurant POS or ticket counter and need fast 160 mm/sec receipts via USB or Serial RS-232C with ESC/POS compatibility.
Skip it if
You need Ethernet/LAN, Bluetooth or Wi-Fi printing out of the box — the CTS310IIEBK ships with USB + Serial only, no network interface.
Also consider
Citizen CT-S751II / CT-S651II for built-in LAN, or CT-S801II if you need a faster 300 mm/sec print speed for very high-volume counters.
