While many normal inkjet printers can also print photos, Photo Printers are printers specially created to print photos. Presently all of these are inkjet printers. They are of a smaller size and use special photo paper in the usual photo sizes like 4 X 6 etc. They allow printing without connecting through the PC by using PictBridge. They also have interfaces to connect digital camera or memory cards, and a screen to preview the photo. Some also allows rudimentary editing of the photo before printing.
