Unable to print

Hello,

To start, I can ping my printers IP, however, when I go to connect to my HP OfficeJet_Pro_7740, I’m presented with “org.cups.cupsd.service” is not running.

When I run

systemctl status org.cups.cupsd.service
Unit org.cups.cupsd.service could not be found.

The cups.service was inactive and masked. I unmasked it and started it, no change.

This seems to have stopped with the last upgrade. Version is Ubuntu 24.04.3 LTS.

I didn’t find anything org.cups.cupsd.service in Help and Support.

What am I missing?

Thanks for any suggestions.

What is reported when you enter

lpstat -t

Also, what do you see when you enter the following in the address line of a browser:

http://localhost:631/printers/

Let's start with the most basic.

Plug in your printer and power it up (not sure, but hoping for auto-detect for the following step).

Try installing/repairing the CUPS installation:

sudo apt-get install --reinstall cups

After that, try the following again to see if you have any Printers showing:

http://localhost:631/printers/

If no printers are showing, then you will need to use the OS built-in "service" for defining/configuring printers.

system-config-printer

As it turns out, re-installing cups got printing working again but it seems like there is functionality that is missing. When I go to

http://localhost:631/printers/  it shows the  printer as being HP-Officejet-Pro-7740-Wide-Format-All-in-one.  When I look that up that printer it says that its not supported any more.  What drivers should I use now?

 Thanks

That printer uses

Apparently, "HPLIP" is required to service devices using "HP PCL 3 Enhanced".


Depending on the situation (your abilities), you might want to consider this, directly from the "source", as a first try:


If that doesn't work, you can then attempt the following sequence:

sudo apt install hplip

sudo apt install hplip-gui

If those don't work, some digging around came up with the following:

which points to this:

I have no idea if that will work, but the claim is that it does.

Note that it is a SNAP package.


If anyone knows anything better for this situation, please share your insights/wisdom.
