Photosmart C4480  with Macbook Pro running BigSur 11.5 via USB connection.  HP Photosmart Driver 5.0.5

Printer had been working fine with this Macbook.  I installed new genuine HP cartridges (74 and 75) and printer went into alignment mode.  Alignment page printed fine (black only -- should there be color?)  but then when I go to scan alignment page, it makes scanning sounds but then tells me "Alignment Page not detected.... Alignment failed...may continue but cartridges not calibrated "  But when I try to print something from computer, whether using both b&w and color, or b&w only, nothing prints.  The page just comes out blank.  I tried turning printer on and off.  No difference, just forced to print out another undetectable alignment page.  I tried uninstalling and reinstalling cartridges...only result was yet another undetectable alignment page.  I tried cleaning printheads twice up to level 3, each time  a black and white only sheet emerged.  When I check HP utility it shows "Supplies: Good" but when I try to open "Supplies Status" in HP Utility, the utility quits and I have to reopen.  Have done 3 times now and it crashes each time.  Please help get my printer working again.  Thank you.
