HP A646 Compact Photo Printer Review
The front of the HP Photosmart A646 is home to the media ports available for use, though both of them are more multi-function than high in number. One port handles the MemoryStick family of media cards, and the other handles the SD/xD (with adapter) family of media cards.
Wireless & Network
Much to users' delight, the HP Photosmart A646 can be used over an 802.11b/g/n wireless network, but that's not even the coolest feature: not wanting to be left behind by other compact photos in the smartphone age, the HP Photosmart A646 allows you to transmit pictures taken with your smartphone to the printer itself, which will then print said picture.
