Star MCP31CI, MQTT, 8 dots/mm (203 dpi), cutter, USB, USB-C, Ethernet, black

Star MCP31CI – A receipt printer built for busy days

The Star MCP31CI is designed for the daily grind of restaurants, cafés and retail shops where receipts need to come out fast and without interruption. At 400 mm/s, the printer keeps pace even on a packed Friday evening — your customers aren't left waiting at the counter.

Paper exits from the front of the unit, which makes installation straightforward even in tight counter spaces. The automatic cutter trims each receipt cleanly after every print — no extra steps needed from your staff.

Connections and compatibility

The MCP31CI gives you three connection options in a single unit:

• ·USB-A — works directly with most point-of-sale systems out of the box
• ·USB-C — ready for newer devices and tablet-based tills
• ·Ethernet — a fixed network connection when the printer is shared between stations or a permanent installation matters

Built-in MQTT protocol support lets you use the printer in cloud-based POS environments without any additional middleware. Star emulation ensures broad compatibility across a wide range of till software.
