ippusbxd has known problems and it will get replaced by ipp-usb where these problems are solved. See the MIR for ipp-usb, bug 1891157. With this replacement driverless printing will work correctly and so most modern HP printers will work without HPLIP at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1878974 Title: Unable to use HP USB Printer in Ubuntu 20.04 - apear to be hplip issues To manage notifications about this bug go to: https://bugs.launchpad.net/hplip/+bug/1878974/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I was unable to get driverless printing working from local machine. I was able to get driverless printing working from Network, but to configure this printer on a WiFi network I required a different computer with working software (was able to borrow a Windows system with working software). Once the printer was on the network (WiFi in this case) I was able to get basic driverless printing working.

Anyone with problems here, please
- If you have a Snap of HPLIP installed, uninstall it, the one I know of

- Remove any HPLIP version installed directly from HP
- Re-install Ubuntu's HPLIP via the command:
sudo apt install --reinstall printer-driver-hpcups printer-driver-

Please post the output of this command here.
- Remove your current print queues with the command:

Replace QUEUE_NAME by the name of your print queue, as it is shown in the
output of "lpstat -v"
- Unplug the printer from USB and re-plug it. Does a new print queue get
created ("lpstat -v" should show it)? Can you print using this queue?
- Could you create a driverless print queue (this queue does not use
HPLIP but common, manufacturer-independent communication protocols of
the printer)? First, run the command
driverless
It should show one or more printer URIs, one per line.
Now run
lpadmin -p PRINTER -E -v URI -m everywhere
Replace PRINTER by a print queue name of your choice and URI by one of the
URIs from the output
of the "driverless" command, the one corresponding to the printer you want to
set up.
Can you print with this print queue?

Eric, the 3.20.5 version of HPLIP you are installing is most probably not for Ubuntu 20.04. Ubuntu 20.04 has Python 2 completely removed and only uses Python3.
