Today, sorry but after restart computer, print doesn't work, like before...
I tried again suppress all lazerjet printers, but no change with the new one.
message when I launch a print: "impossible to start printer, check configuration"

in error logs, I see:

Please put three backticks ````` before and after your terminal output (like the error log output).

What desktop environment is this, Budgie or one of the others?

From what you've described, it seems like CUPS auto-added the printer when it was first discovered, then tried to auto-add it again, and failed (since it was already set up).

Have you tried re-enabling the printer through the CUPS web interface (not the system settings)? That might work. It would be in printer administration.

This week, an updated version of CUPS is being tested in unstable. As mentioned, the current version is very old. If all goes well, the updated version will be synced to stable in the next sync (usually Friday). That may help with some of these printing bugs.

    ok, sorry for th backticks
    Your option works! thanks :-)
    I suppress again the hp printers in Solus control panel (it's Budgie)
    and after search and create the HP printer via Cups interface.
    And it's ok now to print a pdf.

    Before the update of CUPS, I'll maybe have to do this operation after each restart of the computer?

        It is possible that you may have to use the CUPS web UI as a workaround. You'll see if you get an error after the next restart of the computer. I can't say for sure.

          Maybe his printer ip changed for some reason so its trying to set up another printer with new
          ip causing conflict.
          Dunno just thinking.

          Hi,
          Today, printer works after restart computer.
          The printer HP I created yesterday with Cups interface is still there and is working :-)

          I must precise something.

          I've noticed that when I recreate the printer, in its properties, in the "Comportements" (Behaviors) section, the default error policy is "Arrêter l'imprimante" (Stop printer).

          However, when an incident occurs on the printer, it puts it in a state "Pause" and the printing does not occur, it puts itself in queue (idem for the following prints) and I didn't find how to unlock it.

          So I changed the error policy to "Abandonner la tâche" (Abort job) and that solved my problem of print blocking on my printer (HP Officejet 2622).

          Should I have done things differently?

            It's still working.
            But, for information, I see that I have "lost" the possibility to print double-sided. (not available)

            Two answer both of your latest questions:
            It's fine to set the default error policy to "Abandonner la tâche". It saves you the step of having to remove / restart print jobs, and it's working well for you.

            The printer not being able to print doubled sided is a problem. It means the driver currently being used for your driver does not fully support it, or something is turned off. Here are some things you can check.

            • HP Device Manager settings:
              (If you get error 5012, ignore this, it's a bug in the software)

              • Open HP Device Manager from the application menu, click on the icon for your printer
              • Go to the Print Settings tab, and under that click the General tab. Do you see the Two-Sided option there?

            • Printer Settings:

              • In Printer Settings, right click the printer and go to Properties.
              • On the Installable Options view, do you see Duplex Unit? If so, is it checked? If not, check it there and click OK

              I see the upgrade of HPLIP and CUPS last Friday.
              So I suppress all the HP printers I had.
              I tried to insall it with HP device manager, but it don't find any printer. No printers are listed inside.
              So I install it with Cups manager on http://localhost:631/
              I choose the cups driver, and it's done
              And now I can see in the two-sided option in options for print.
              Via Cups manager, I have installer too another printer "version", with Post script driver, it seems ok too.
              With Solus printer manager, it install printer too, it seems ok too.
              So I have 5 versions now, with 4 who seems to be ok.
              I don't know which is the better one...
              I will try in use.
              Thank you

                  David26 Many printers are compatible with several different drivers. If a given driver works and supports the the features you need from the printer then it's good enough, no need to try to figure out which is the "best" driver.

                      Yes, that's true.
                      HP device manager (hplip) doesn't recognize printer HP, so I can desinstall HPLIP now with no risk?

                          David26 Hplip gui install printer if I remb right its a network printer
                          when install select network it takes you to another screen at the bottom I think its manual or something
                          and put in the printers ip addy hplip will find it. (mine has trouble finding it auto to but always does this way)
                          and install it.
                          I dont understand why you have so many printers listed (If I understood that right)

                            Since you have set up your printer successfully with CUPS it should be safe to uninstall hplip. If you ever need to scan with an HP you will need to reinstall it
