Small enough to fit in a pocket, if you have large pockets, the SELPHY Square QX10 lives up to its name by outputting square photo prints with a size of 2.7x2.7 inches (68x68mm) direct from your mobile phone.
Good image quality, Very easy to use with Canon’s companion app, Fairly speedy
Quite pricey to buy, No option for connecting to a computer, A little bulky for a ‘pocket printer’
