The WPS Pro eliminates the need for a laptop and software.  You can use it with DNP's 620a, DS40, DS80 and RX1 printers. You can connect two printers to the WPS Pro and it will automatically pool the printers. Please see this article for more info or on DNP's website here.

Fotozap also works well with Airprint printers including the mini Canon Selphy printer, Inkjet photo printers, as well as professional printers if you use a laptop-based printer server that supports Airprint.
