Consumers are often surprised at the price of replacing their printer cartridges, especially when compared with that of purchasing a brand new printer. The major printer manufacturers, Hewlett Packard, Lexmark, Dell, Canon, Epson and Brother, often break even or lose money selling printers and expect to recoup their losses by selling cartridges over the life span of the printer.

Most consumer inkjet printers, (but not Epson printers) use a thermal inkjet; inside each partition of the ink reservoir is a heating element with a tiny metal plate or resistor. In response to a signal given by the printer, a tiny current flows through the metal or resistor making it warm up, and the ink immediately surrounding the heated plate is vapourised into a tiny air bubble inside the nozzle. An ink droplet is forced out of the cartridge nozzle onto the paper. This process takes a matter of milliseconds.

• Typically, two separate cartridges are inserted into a printer: one containing black ink and one with each of the three primary colours. Alternatively, each primary color may have a dedicated cartridge.
• Some cartridges are specifically designed for printing photographs.
• All printer suppliers produce their own type of ink cartridges. Cartridges for different printers may be incompatible - either physically or electrically.
• Since replacement cartridges from the original manufacturer of the printer are often expensive, some other manufacturers produce "compatible" cartridges as inexpensive alternatives
• Some cartridges have incorporated the printer's head (most HP, Dell and Lexmark printers use this system). Usually, they are more expensive, but the printers are cheaper. Others that don't include the printer head are cheaper but the printers are more expensive (for example, most Epson printers).

When the ink first begins to run thin, the cartridge should be refilled or replaced, to avoid over-heating damage to the print-head.

Many consumers opt to have their cartridges refilled or purchase remanufactured cartridges from third parties to save money over buying new cartridges.There are several qualities and types of refilling, some of them being safe and successful, while other types can ruin the printer and/or give bad quality prints. Options include taking empty cartridges to "refillers" or "remanufacturers" who pump in new ink and buying store-branded ink..

Laser/toner cartridges sold as "compatible" are usually re-filled cartridges. Inkjet cartridges sold as "compatible" are newly manufactured cartridges. Inkjet cartridges sold as "Remanufactured" are cartridges that have been used at least once by a consumer and then refilled by a third party.
