The Canon CP-400 is a dye-sublimation printer. Dye-Sublimation is a technology that uses a matched color ribbon (donor) and photo paper (receiver). As the paper passes through the printer, the ribbon is heated to a gas state. The gas permeates the photo paper before returning to a solid state. The result is an image that looks just like
a 35mm print and is typically as archival as 35mm prints. The CP-400 prints a 4x6 inch image in about 85 seconds. Prints cost only .38 cents each.
The Canon CP-400 can print from a computer (USB connection) or directly from digital cameras that support PictBridge direct printing (most Canon digitals, Nikon D50 & D70s, etc.).
