Canon, HP, Xerox and Brother are just a few names of companies who make color ink cartridges. Epson and Sophia are two others who make color ink printer cartridges.
The Epson photo printer uses a lot of ink cartridges for color. There are four different color cartridges that you must buy and they are black, blue, pink and yellow. That is more than the standard of two cartridges for most other color printers.
Photo printers are not limited to photos. Instead of having a single tricolor cartridge (2 cartridges total, 1 black + 1 tricolor), they have individual color cartridges (usually 3-6). The cartridges can be cheap since they're small but it can be a pain to have to keep replacing individual cartridges. If you're not going to print photos, don't get a photo printer unless you really like the other features the particular photo printer has. If you don't need color, consider getting a laser printer. The cartridges cost more but once you take how long they last into consideration they cost less.
