Woosim WSP-R241 Pocket Printer

The latest mobile thermal printer from Woosim draws on the aesthetics of their popular semi-rugged WSP-R240 device. The WSP-R241 is a single skin version of the original casing making it even lighter and its compact dimensions make it ideal for carrying on the belt, hand held or in a pocket.

The standard sized 57/58mm wide thermal rolls are very low cost and easily obtainable. The printer has a simple push button to open the cover and the easyload system means the new roll is simply dropped into place, the lid closed and its ready to print!

The WSP-R241 has been launched with a USB and Bluetooth dual interface. Alternative interface versions will be announced later. In common with Woosim's range of other mobile printers, the R241 comes complete with high capacity Li-ion batteries as standard. This means the printer can be used for prolonged periods before recharging (which only takes 4 hours).
