Woosim WSP-SM and WSP-SC Mobile Printer Series

The Woosim 1 inch mobile printers are pocket sized and ultra light-weight making them ideal for truly mobile applications. They are based on a very fast (80mm/sec) direct thermal mechanism printing on 37mm wide paper rolls.

Both models include a magnetic stripe reader and the SM-125 also has an integrated ISO 7816 Compliant (EMV level 1 Certified) smart card reader. This version incorporates a SAM (Security Application Module) card slot for secure, fiscal applications. The printers have an RS232 interface and a data cable is supplied but they also have a Bluetooth interface as standard. The wireless capability makes the range ideal for mobile receipting, door to door selling (or collecting) and outdoor event POS.

With high capacity Li-Ion batteries as standard, the printer can be used for a prolonged period before recharging (which only takes 4 hours).
