The Epson WF-7720 has a decent inkjet cartridge system. There are three separate color cartridges, so you only have to replace the ones you use most often. Their combined page yield is quite good as well. Unfortunately, the black cartridge’s performance is disappointing. Thankfully, if you run out of black ink during a print job, the printer will request to use the photo black or color cartridges to finish the active job. There are also high-capacity and extra-high-capacity versions of the black cartridge, which should last longer.
This printer accepts third-party cartridges, but this could void its warranty, and special attention must be paid as this printer uses pigment-based inks.
