Star Sanei SK5-31UD-LQW-H-SP3, 8 dots/mm (203 dpi), cutter, presenter, USB, RS232

Star Micronics SK5-31UD-LQW-H-SP3 — Kiosk Receipt Printer for Restaurants and Self-Service Points

The SK5 is built to be integrated permanently into a service point — a self-service kiosk, ticketing terminal, or a dedicated print module in a checkout line. Once it's installed, it just works. There's no adjusting, no babysitting, no staff needed to hand over a receipt.

Keeps the queue moving

The print mechanism is engineered for sustained daily load. At up to 250 mm/s, a receipt is out and in the customer's hand before they've finished gathering their things. The built-in automatic cutter trims each receipt cleanly, and the presenter pushes it forward within reach — no jams, no half-cut paper curling back into the slot, no intervention required.

When you have dozens or hundreds of customers passing through a self-service point each day, small delays compound. A printer that handles the mechanical side without fuss means your flow stays intact from open to close.

Installation and setup

The SK5-31UD uses an installation print mechanism — it's designed to be integrated into a larger assembly rather than placed on a counter as a standalone unit. That means setup is a more technical undertaking than a standard desktop printer. Vaivatta handles the integration and confirms the printer is running correctly within your existing system before we're done.

The right fit for a busy self-service point

If your service point sees a steady stream of customers and you need a printer that handles its job without drawing attention to itself, the SK5-31UD is built for exactly that. Japanese manufacturing and Star Micronics' experience in high-volume print mechanisms show in the durability of the unit — the mechanism holds up under daily wear, and the Black Mark Sensor makes sure every receipt lands in the right position, every time.
