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.
Excerpt: Canon's CP400 is only about the size of a thick paperback book, but its long input tray means it occupies about twice the desk space. Like the Dell and Kodak dye-sublimation printers, photo paper passes out of the rear during printing, so a further small area must be kept clear. The CP400 has no memory card slots or preview screen, but it is the least expensive printer on test.
