A photo printer is a printer designed for high quality digital photo printing on photo papers. The conventional inkjet printers and the modern digital printers require printer supplies that include inkjet refills and cartridge refills. There are several different models of printers requiring different compatible printer cartridges. These can either be new or remanufactured cartridges. Whether a person acquires a new or a remanufactured cartridge will depend on several factors. Before the era of digital printers, only the standard inkjet printers existed. The coming of photo printers brought a revolution and the birth of digital cameras even increased their use. Initially they were more expensive than the inkjet printers but they later dropped in prices when one company started offering less expensive photo printers. All major manufacturers of printers then followed suite and people really bought the printers.

Currently there are photo printers which print 4" x 6" photos. These compact printers do not require a computer at all and can also be found in larger sizes which can print 8" x 11", 10" x 14" and even larger photo sizes. The larger paper-size printers are manufactured by all major printer manufacturers which can handle different photo printer requirements. These printers are usually so good they have a guaranteed lifespan of over 100 years.

There are several significant differences between the standard inkjet printers and photo printers. To start with, photo printers use more printer cartridges than standard inkjet printers. They also make use of colors like light magenta, light black, photo cyan and yellow to be able to produce more realistic and vivid pictures. Standard inkjet printers use tricolor cartridges. Another plus on these printers is that they have digital memory cards that enable the printing of pictures without the need for a computer. Standard inkjet printers must make use of a computer to print.

Some photo printers have the capability of printing directly from cameras that support PictBridge protocol. PictBridge is a standard set in the photo industry by the Camera and Imaging Products Association (CIPA) on direct printing, which allows printing images directly to the printer from digital cameras. The majority of standard inkjet printers do not have these features. One of the latest printer technologies in the market today is photo printers that can print without using ink. The inkless printers are much smaller than conventional ink printers which make them both portable and convenient. The photo printers that are usually referred to as portable or mobile are printers that use wireless technology using signals instead of cables to print. However, most of them are just as big in size as conventional printers.

The inkless photo printer is a real portable printer that can comfortably fit into a purse or a pocket. The maintenance of these inkless printers is very easy since there are no printer supply costs and no toner refills or cartridge refills required. The best part of it however, is that no ink is required and thus no inconveniences are caused when looking for cheap remanufactured compatible cartridge.
