Review on 🖨️ GPC Image Remanufactured Ink Cartridge Replacement for HP 972X 972A 972 - Compatible with PageWide Pro 452dn 452dw 477dn 477dw 552dw 577dw 577z 552dn Printer - High-Quality Ink Set (Black, Cyan, Magenta, Yellow) by Michael Ringgold

I just couldn't bring myself to buy OEM replacement cartridges at such a ridiculous price so I went with them. Upon installation, the printer recognized that it was not OEM, but they seem to be working fine. I don't print high quality images so I really can't tell what the difference in results is between them and HP. I estimate that by running 2 sets I've saved about as much as a new printer so I'm not worried about the warranty. You can make your own decision as long as I'm satisfied.
