Conclusion: The Canon Selphy CP400 gets most things right for a printer designed for up to 4- by 8-inch photo output. It prints quickly, and most photos qualify as excellent, but cost per print is relatively high.
Pros: Prints from PictBridge cameras. Easy to set up and use. Thermal-dye output is smudge- and waterproof. Photos double as postcards.
Cons: Doesn't print from memory cards. As with most thermal-dye printers, print cost is relatively high. Output quality is uneven.
