Last week, I got my new iMac 24’. The setup was very easy. I transferred my User Account and the Applications from my old iMac using Apple 'Migration Assistant’. No headaches.
Yesterday, my Hp Color LaserJet CP1515n printer did not print correctly. I could not print envelopes. The page setup was correct but the result was wrong. I decided to reinstall the driver and update of the printer’s Firmware. While updating, the printer blocked and when I restart it, the result was: "Firmware Corrupt, Ready 2 Download".
