gotcha!

added admin to the group lp, restarted eos

PPD: /etc/cups/ppd/DeskJet_4100.ppd
warning: Failed to read /etc/cups/ppd/DeskJet_4100.ppd ppd file
PPD Description: 
Printer status: printer DeskJet_4100 is idle.  enabled since Fri 02 May 2025 09:04:19 PM PDT
error: unable to open channel
error: Communication status: Failed

No dice! =[ Could this file not even exist, or corrupted?

Look at: An alternative solution. Set up the printer as a driverless printer.

here:

https://unix.stackexchange.com/questions/600952/how-to-install-python3-pyqt4-on-linux-mint-20-hplip-dependency

It’s an old post, so it may or may not work for you.

26 aur/pyqt4-common 4.12.3-7 (+20 0.00)
    Common PyQt files shared between python-pyqt4 and python2-pyqt4

Might help, might not.

I’ve tried installing normal driver and driverless through CUPS and neither works for communication even though it detects the printer and installs it.

i built the pyqt4-common package and unfortunately i still get the same errors. dbus may not be installed or isn’t running. python3-pyqt4 needs to be installed. and cannot read the pbb file.

the diag reads 100 things about the specs on the printer yet somehow cannot read the pbb or communicate. printer used to work fine. really confused on this one…

Guys I’m not sure which of these steps worked, but today I checked on the printer and its working again! Maybe it was the pyqt4-common package. Either way huge thanks to you guys!
