Star Sanei SK1-V311SF4-Q-M-SP, 8 dots/mm (203 dpi), cutter, USB, RS232

Star Micronics SK1-V311SF4-Q-M-SP — Kiosk Receipt Printer for Daily Use

The SK1-V311SF4-Q-M-SP is a direct thermal printer built to install inside kiosk enclosures, self-service terminals, and automated machines where space is tight and reliability is non-negotiable. The print mechanism mounts into the host unit's chassis, keeping everything compact and tidy — no external printer box taking up counter space.

At up to 250 mm/s, it keeps pace even during the busiest periods. Receipts and barcodes come out sharp and readable at 203 dpi (8 dots/mm). Maximum media width is 83 mm and print width 80 mm, with roll capacity up to 120 mm in diameter — fewer roll changes, less interruption.

Connectivity and Paper Sensing

The printer supports both USB and RS232, so it fits into most kiosk control systems without adapter gymnastics. The built-in Black Mark Sensor reads the paper's position on every cut, which means receipts separate cleanly at the right point every single time — no ragged edges, no blank trailing strip.

The built-in auto-cutter handles the cut itself, so customers never need to tear the paper. In a self-service context, that small detail keeps the experience smooth and the area around the terminal tidy.
