Unable to Print To an HP Laserjet

Done the upgrade and just get these warnings which I assume are normal and nothing to worry about.

Yes, you right. Personally... They annoy me. So I usually go ahead and take care of them. But generally, they often act as a placeholder.
You can see a thread on it here:

Linux-firmware sources

Some of us will occasionally experience the i915 "Possible Missing Firmware" warning. EDIT: A recent Update may make some of this Obsolete. If you are reading this after the updates released by 16 Dec 2021 and still having Firmware Warnings, perhaps the below will help you. I gathered all the listed files into one directory and this can be handled here: However, this only covers users with the i915 modinfo warning. Others have the AMD warnings and so forth.

This is the write up for HP-CHECK which I would like to run before I run hplipxx.run but I dont understand this :- Run as python ./check.py

hp-check: Dependency/Version Check Utility (ver. 15)

Check the existence and versions of HPLIP dependencies. (Run as 'python ./check.py' from the HPLIP tarball before installation.)

Usage: hp-check [OPTIONS]

[OPTIONS]

Compile-time check:	-c or --compile
Run-time check:	-r or --run
Compile and run-time checks:	-b or --both (default)
Fix the found issues on confirmation:	--fix
Set the logging level:	-l or --logging=
	: none, info*, error, warn, debug (*default)
Run in debug mode:	-g (same as option: -ldebug)
Output plain text only:	-t
This help information:	-h or --help

Notes:

1. For checking for the proper build environment for the HPLIP supplied tarball (.tar.gz or .run),
   use the --compile or --both switches.
2. For checking for the proper runtime environment for a distro supplied package (.deb, .rpm, etc),
   use the --runtime switch.

[Aravisian]

At any point, had you tried installing hplip from terminal?
I wonder if it may provide a bit of ease, if you have not tried it already:

sudo apt install -y hplip hplip-gui

[RTB]

Thanks.
This could be helpful if I knew how to get into the HPLIP GUI after install. I type hplip-gui and nothing. I saw there was a hplip-gui in the packages manager software and installed that and tried to launched that and that just starts to do something and then closes again.

[Aravisian]

If launched from terminal with hplip-gui, do you see any errors?

[RTB]

It says hplip-gui command does not exist.

[Aravisian]

I try to be helpful...
This can happen when the village idiot (me) is eager, but ignorant. I do not use an HP Printer, so I am out of my element on this one...

You can run sudo apt clean && sudo apt autoremove to get rid of some of that clutter if you like.
The following portion states you have hplip-gui installed...
Try

hplip --gui

or

hp-setup --gui

[RTB]

I am getting this error when running hplip-3.22.2 again :-
Gtk-Message: 16:14:27.070: Failed to load module "canberra-gtk-module"

Can I do the following without any risks of causing other issues for other software.

sudo apt install libcanberrra-gtk*

[Aravisian]

That's no problem. You can run

sudo apt install libcanberra-gtk-module

[RTB]

I did this and a number of tried twice with the hplip setup script. The hplip make works OK but when I get to setting up the printer I get all sorts of errors depending on why route I take either the gui or command line.
Using command line I get :-

error: Channel write error

error: Channel write error error: Channel write error error: Device is busy or in an error state. Please check device and try again.

I have done a search on this and cant find anything. I know that USB cable is fine and also the printer as I have been able to print via my Windows VM on VirtualBox.

[Aravisian]

I think we have two threads facing the same issue:

Error No System Tray Detected on this System

I am trying to setup my HP LaserJet printer using the HP--SETUP and getting No System Tray Detected On This System and also unable to open device as the screenshot shows [Screenshot from 2022-03-09 16-48-01]

Sometimes, the HP Printer must be hard reset prior to installing the driver. The infamous, did you turn it off then back on again?

This can happen because the printer programmer is quite simple and during setup, gets it into its head that it has a filled queue.

Another thing that can happen, is in multiple attempts to install the drivers, the system gets confused about the configuration. The remedy is to completely remove the drivers, then install fresh and in one attempt:

How to install latest HPLIP on my Ubuntu to support my HP printer and/or scanner?

[RTB]

I have started going through the askubuntu article and have come to the python part trying to ascertain which python version I am running. It says command python not found.

Does HLPLIP still use Python?

[Aravisian]

Yes, it does. In terminal, can you run

python --version

[RTB]

I had to use python3 as the command.
Maybe this is because of what I did with the
python --version

Command 'python' not found, did you mean:

command 'python3' from deb python3
command 'python' from deb python-is-python3

raymond@RTB:~$ python3 --version
Python 3.8.10

Is this right?

[RTB]

I am still getting systray issue after rebooting and Channel errors so it cant communicate with the printer. I have tried printing a test page. hp-check comes up clean except the channel errors.

I was thinking that we should close this issue and start a new one. What do you think??

[Aravisian]

@RTB

I was thinking that we should close this issue and start a new one. What do you think??

@RTB

Import Error: /usr/lib/python3/dist-packages/hpmudext.cpython-38-x86_64-linux-gnu.so: undefined symbol: mdns_lookup

I may be wrong, but it looks like the same underlying issue needs to be addressed.

[RTB]

Where did you see the mdns_lookup error message? I have not seen this since I had installed network-snmp package and reinstalled hplip. I have only got these errors

I think the second post - but quoted it as it is a python import error.

[RTB]

I think I am going to throw the towel in on all the open issues for the HLPLIP install, setup and customisation. Could I just use cups to print on this HP printer. I dont need any other functionality support. I can always use the Windows VM for scanning as an example.
