Error code: 0x800f0922
the laser printer is used daily in a small office and people are complaining, the HP driver had all the features we need. the Windows Update one is basic... ive reinstalled the vendor one twice and it keeps getting replaced, is there a way to block just this driver update? bonus question: why does it do this in the first place? seriously need help here 馃槶
