Hi,
Subject says it all. I got a HP Officejet Pro 9120e recently and tried to get it setup on a CentOS-Stream 9 machine.
I got it on the net and recognized by Cups. In the list of HP printers in Cups there is no entry for the 9120e, so I picked the nearest model, the 9020.
Now simplex printing is working fine black/colour.
Duplex printing has problems. When I print a two page document to the duplex printer the document prints OK but there is some overprinting/underprinting which makes the printed document unusable.
The problem is probably with an incorrect ppd file for the duplex printer.
Regards
Tony.
