I own an EPSON XP-2105 printer and bought these printer cartridges from STAROVER. The print quality does not differ from the original cartridges and you pay the same for 5 STAROVER 603XL cartridges as one original EPSON XL cartridge costs. If the print quality is not immediately convincing, you should clean the print head of the printer or perform a nozzle test so that the printer can adjust to the new cartridges used. I print several lecture slides a week in color and black and have not had a single problem.
