Review on 💯 High-Quality Compatible 972X Ink Cartridges Replacement for HP 972A – Work Efficiently with HP Pagewide Pro Printer Models 452dn, 452dw, 477dn, 477dw, 552dw, 577dw, P55250dw, P57750dw – 4 Pack (1 Black, 1 Cyan, 1 Magenta, 1 Yellow) by Carmen Jones

I use a lot of ink, especially color ink, and I buy at least a full set of color and every two or three black every month, so I needed a cheaper way than PS brand. They worked with my Pagewide Pro 477dw. I only had one problem. I haven't had the black replacement yet as it was about half full and should last a few more weeks. I was in the middle of a print job when it suddenly said there was no black in it. I ran to the store to get a replacement (brand name) and when I got the "empty" one I felt like it was still heavy with ink. I tried to paste it again several times but it still came up blank. Inserted XP and finished the job. When I later worked on it, I finally got this "blank" working again. I'm not sure which block it was and I might even buy them again, but I'll make sure I have a backup just in case.
