Conclusion: The printer hardware is pretty solid and works smoothly giving Drug Store quality photos. Unfortunately the development team needs to beef up their software staff. Already obsolete because it doesn't support Windows 8. Doesn't display some files on the built in screen. Difficult to crop.
Pros: Small Footprint
Cons: Difficult to use, Difficult Setup, no windows 8 os support
Summary: I bought this compact printer to upgrade from my old Canon Selphy. My old one did not have a built in USB port. However, I was disappointed with the USB port. I had a USB port that had pics that would load onto anything else but when I put the USB flash drive into the CP900, it kept saying it was...
Summary: The Canon Selphy CP900 prints well, but was very disappointed to learn that each time you power off the printer, it uses up the ink for another picture when you power it up again. This is a very bad design flaw. Canon only sells packs of ink and photo paper together.
Summary: The main advantage of this product over the CP800 is the WiFi support. If you want to print from a smartphone (I used Android) then you are in luck. The application is simple and intuitive and with Android you can send the image from any application using the Share feature.
Conclusion: I purchased the Canon Selphy CP900 back in late 2012, and it worked well on my WinXP machine. But then I purchased a new Win7 computer, and it worked well with that. I was eligible for the discounted Win8 upgrade, but was a little wary.
Pros: Easy Setup, durable, High Quality Output, fast print speed, easy to use
Summary: Printer is very small, instructions inadequate. The system is unusual in the way it applies ink but the prints are fine. The printer does NOT come with ink cartridge. Cartridge can only be puchased through Canon and comes with the paper. You cannot purchase ink or paper separately.
