HP A646 Compact Photo Printer Review
As far as compact photo printers go, the HP Photosmart A646 competes well with the better-performing models of the bunch, and with the added convenience of having all of the drivers stored on the machine itself, as well as the ability to print from a smartphone, the Photosmart A646 is a very solid pick amongst the compact photo printer market.
It doesn't have the absolute best performance out there, but it does a fine job with 4 x 6 and 5 x 7 prints, which is all that consumers considering the HP Photosmart A646 will ask for. It's a little on the slow side, but the quality and convenience gained by purchasing the HP Photosmart A646 is more than worth it.
All that aside, if you want to print documents or photo prints larger than 5 x 7, you're going to need a different printer.
