Woosim WSP i series Rugged Thermal Printers

The WSP-i family of rugged industrial printers are certified IP54 resistant to water and dust. They have been tested to operate from -30 to plus 70 degrees C and can also withstand a drop of 1.8m onto concrete making them ideal for mobile receipting, door to door selling (or collecting) and outdoor event POS.

They have RS232 and Bluetooth interface as standard with USB or Wireless LAN options available. Other options on selected models include magnetic stripe reader (MSR) and Smart card reader. With high capacity Li-ion batteries as standard, these printers can be used for a prolonged period before recharging (which only takes 4 hours).

The WSP-i350 and WSP-i450 models are certified by Apple Inc.; "Made for iPod", "Made for iPhone", and "Made for iPod" which means that an electronic accessory has been designed to connect specifically to iPod, iPhone, or iPad, respectively, and has been certified by the developer to meet Apple performance standards (Note *1).
