Star Sanei SK1-311SF4-LQP-M-SP, 8 dots/mm (203 dpi), cutter, presenter, USB, RS232

Star Sanei SK1-311SF4-LQP-M-SP — kiosk receipt printer for demanding daily use

This Star Sanei printer is designed to be installed inside kiosks and self-service terminals where reliable, fast printing has to happen without anyone watching over it. The mechanism mounts directly into the enclosure, making it a practical fit for custom builds in cafés, restaurants, and retail environments.

Fast, clean printing — every time

Direct thermal printing means no ink cartridges and no ribbons to replace. Fewer consumables in the mix means fewer reasons for the unit to go down mid-shift. At 250 mm/s, the receipt is out and in the customer's hand before the next person steps up. Resolution of 8 dots/mm (203 dpi) keeps text sharp, barcodes scannable, and simple logos presentable.

Auto-cutter and presenter included as standard

The automatic cutter trims each receipt cleanly after every print — no tearing, no ragged edges, no jammed paper to sort out. The presenter guides the receipt through the dispenser slot in a controlled path, which matters in kiosk installations where the paper route needs to be predictable and consistent every single time.

Connections that work with what you already have

Both USB and RS232 interfaces are built in, so the printer slots into most existing POS setups regardless of how your system connects. The Black Mark Sensor reads pre-printed cut marks on specialist receipt rolls when you need precise ticket or voucher positioning. A Molex adapter is available separately if your installation requires it.

Installation and getting started

Because this is an installation mechanism — not a standalone desktop unit — it fits best into new kiosk builds or hardware refreshes where you have access to the enclosure during assembly.
