The Canon PIXMA TS6320 has an acceptable inkjet cartridge system. Since it has multiple color cartridges, including a black photo cartridge, you only need to replace the empty ones, which can help save costs. While the page yield of their standard black replacement cartridge is pretty bad, you can print a surprising number of copies in color. There are also extra high-capacity cartridges available which can help extend its print yield.
This printer will accept third-party cartridges, but this could void its warranty, and special attention must be paid as this printer uses a combination of dye and pigment-based inks.
