A fresh install of latest Ubuntu usually gives me some sort of printer issues. This time it would spend some time Processing the job and then Stop. This is what i did this time:
1# install drivers
2sudo apt install hplip
3sudo apt install printer-driver-gutenprint
The hplip package (HP’s Linux Imaging and Printing software) is usually already installed on Ubuntu. I tried updating it by downloading and installing the latest from HP Support but it wouldn’t install as Ubuntu 21.04 wasn’t supported and the dependencies won’t install.
The other one printer-driver-gutenprint was mentioned here and it provides CUPS drivers for Canon, Epson, HP and compatible printers.
I think installing this printer-driver-gutenprint package did the trick.
