Woosim WSP-R231 & WSP-R241 Pocket Printers

The replacement for the immensly popular Porti S40 from Woosim draws on the aesthetics of their popular semi-rugged WSP-R240 device. The WSP-R2x1 are single skin versions of the WSP-R240 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 printers have 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, they come complete with high capacity Li-ion batteries as standard. This means they can be used for prolonged periods before recharging (which only takes 4 hours).
