Enchanted by this printer, small in size, big in quality. The wifi works well, but think to choose the suitable mode (ad hoc or infrastructure). For example, the iPhone allows use in ad hoc fashion (direct connection iPhone / printer) but android smartphones only work in infrastructure (in a network with top box or other box). The photos are good quality, and just prepare with image processing software or softwares supplied with the printer (warning, to install ImageBrowser, you need a gun camera ...)
