The Canon CP-330 is a mid-level, portable dye-sub photo printer. The main difference between the entry-level CP-220 and the more advanced CP-330 is the included battery pack intended for increased portability. The CP-330 can be operated on the road with a car adapter if purchased separately. As a small format printer, this device is capable of printing credit card sized prints (2.1" x 3.4"), mini-stickers (0.9" x 0.7", 8 per sheet), 4” x 6” prints and also 4" x 8" prints. The CP-330 comes with one 4” x 6” combination photo paper/ink cassette and one 4" x 8" pack, but additional cassettes can be purchased if one needs different sized paper or refills. The standard 4” x 6” pack of 36 prints costs approximately $12, making each photo $0.33. Printing can be accomplished with a computer or directly from a Canon camera via USB.
