Designed specifically for high-demand retail counters, hospitality, ticketing, and healthcare workstations, this commercial-grade printer handles extra-wide media up to 112 mm (4.4 inches) across.

Engineered with Citizen’s modern flat-top aesthetic and a spill-resistant front-exit mechanism, the CT-S4500 prevents liquid splashes and foreign contaminants from entering the paper path—making it ideal for under-counter integration or busy food service stations. An intelligent built-in A4 document compression driver automatically scales down wide, multi-column reports into compact 4-inch printouts without requiring layout redesigns.
