I am using Ubuntu budgie 18.04.1 on my HP Compaq Presario laptop. From Windows I shifted to Ubuntu first several years ago, and for about two years I am using Ubuntu budgie 18.04.1
HP printer installation is causing a problem. I downloaded HPLIP version 3.19.6 run and asc files latest from HP site but landed in a problem with plugin failed in installation. There was also a problem with downloading firmware.
Help me to uninstall all old versions of HP and do a fresh install.
You havent explained why you need to manually install. As I said your printer is supported out of the box … there is no apparent reason that i can see why trying to manually install is needed.
