Thread: After Kernel upgrade printing problems

  1. #1

    Default After Kernel upgrade printing problems

    Leap 4.1 KDE Plasma 5.5.5, kernel 4.1.36-41-default
    In the past month I think the kernel has been updated what, 3 times, 4x? I do not know when my problem arose.

    Somewhere during those recent kernel updates I lost my ability to print.

    I fought and fought this and am partway there. But problems remain.

    What is now finally working again....My network connected HP laserjet printer by re-running HPLIP device setup.

    What continues to be a problem, maybe a bug?.....

    In systray, I choose printers, click on the printer, and choose configure.
    Nothing happens. But.....when I shutdown (also if I logout or restarting), when the background closes, I find (hidden under the background image) the config printer dialog box is displayed just prior to the shutdown (or restart, or logout).

    So config printer does not get the focus and remains hidden. There is no indication on the task manager bar at the bottom of my screen that there is a dialog box open.

    Is this a bug and is there a simple way to bring it to the foreground?
    This same situation exists if I choose the printer from 'configure desktop'.

    My desktop background is the standard black background with the lightbulb showing gecko as a bulb filament.

    I'm a bit confused by your need to reconfigure the printer. Are you not able to print from an application? Is CUPS active?

    What does the following report?
    Code:
    lpstat -t

    I can't replicate this. It works as expected for me, (although I don't generally use the printer utility). Perhaps a graphics-related issue? Which graphics card/driver?
    Code:
    /usr/sbin/hwinfo --gfxcard

    I'm a bit confused myself and why I posted here. After I upgraded the kernel, no, I was not able to print from an application. My first step was to open the printer config in the systray. That did nothing, only to later discover it 'hiding' behind the desktop wallpaper and visible only as the desktop was closing. After redoing the printer setup in HPLIP I can now print in an application.

    I was wondering if there was a bug since it worked fine for a long time and after one of the last several kernel updates my printing was broken. Since you can't replicate it then I guess it may not necessarily be a bug.

    So you are able to see the popup for printer config when choosing it from the systray?
    Maybe I have to go to noveau. I have long forgotten why I switched to fglrx, I seem to recall I had some sort of issue w/ noveau but don't recall what it is. Apparently I'm going to have to dump fglrx at some future point because I hear it doesn't work with 42.1.

    Forgot to mention: Config printer now works properly when selected from the systray.

    I spoke too soon. After checking systray printer configuration, I went back and checked it a 2nd time. Now it is failing again and printing is failing again. I cannot print from apps, for example, kwrite.

    Additionally, the hp device manager will not open. I am back to square 1, unable to print a test page, even from YaST printer page.

    Print to file, creating a pdf still works ok.

    I don't see an update in YaST for hplip. I currently am using 3.14.6-3.10 dated 2014.
    At hpopensource.com I see there is a much newer version but I'd rather stick to something released by opensuse.
    Is there a repo I should possibly check for hplip?

    Yes, that looks ok to me.

    No, the nouveau driver is for NVIDIA hardware. You have AMD hardware, so the free radeon driver or proprietary fglrx driver are your choices.

    Try printing a test page via the CUPS web interface (via a browser)
    http://localhost:631/printers
    Click on the printer > 'Maintenance' > 'Print Test Page'

    I don't see an update in YaST for hplip. I currently am using 3.14.6-3.10 dated 2014.

    I don't think that is the problem. It seems to be the desktop behaving badly with the proprietary driver?

    I was unable to print the test page from CUPS.

    I reinstalled CUPS using YaST, and I reinstalled my networked printer using YaST.

    Now I can print a test page in CUPS.

    The hp-toolbox still is not working correctly and I installed the latest version outside of the repositories, something that I usually try not to do.

    The updated version of hp-toolbox does not locate my printer so I assume there is some issue with it and I will remove it from my system.

    Now, when I open Configure Desktop -> Printers. I was able to get the configuration screen to open, the first time. When I closed that app and restarted Configure Desktop I was unable to open Printers. I do not know if there is something hidden behind my desktop background, I will need to logout or restart to check that. But at least I can print, for the moment.

    I doubt reinstalling CUPS was necessary. Are you sure cupsd was running? If it happens again just check with
    Code:
    systemctl status cups

    Perhaps you have a firewall active? That can prevent 'automatic' discovery. However, you should still be able to reach/configure your printer by IP address.

    Share your configured repos, just in case there's something behind this odd behaviour...
    Code:
    zypper lr -d

    Another thought - try creating a new user and see if this strange behaviour exists there.
