This printer is based on the principle of zero ink, which is very excellent results. It can be connected in 3 ways: directly at the camera (compatible PictBridge), Bluetooth (the best is to add a Bluetooth dongle to your computer if it is not the original interface) by USB (less convenient method: you have to find the software on the Internet, and manipulation succeeded in Win 7 32 bits, but failed on my XWin August 64 bits). Getting the picture is very fast. The only drawback: the format is a little small (10X7.5), but it is to have a picture in his wallet. The printer is very convenient; the price of the photos is a little High.
