    [SOLVED] Printer not visible in KDE apps

    Hi,

    I have a really strange problem with a printer (HP PSC 1355) not showing up in any KDE application. It works fine from other apps, like OpenOffice or Firefox, but not in any of the tested KDE apps like KMail, digiKam and KSnapshot.

    If I run the KDE printer manager (through System Settings>Printers), it's not visible either until I go into administrator mode. Then it shows up. Under Properties/Users it say "All users allowed".

    I have tried removing it and recreating it. I have tried creating it from CUPS directly in my browser (localhost:631), from gnome-cups-manager and in HPLIP Toolbox. The printer show up as before, working in all apps except in KDE apps.

    As far as I know I have done nothing strange with this machine. It's running standard KDE 3.5.10 and is fully updated.

    Can anyone crack this?

    Regards,
    Tobias

      Re: Printer not visible in KDE apps

      Hi ntzim,

      Thanks for the good tip. I'd forgotten to check those logs.

      Yes, I found something strange. The error_log contain some suspicious lines. When doing an operation from the KDE printer manager, for example Stop/Start Printer, an error is logged but it seems to work anyway. If I do "stop" in the KDE printer manger and then check the CUPS web page, the printer has indeed been paused. Actually, the same error is logged if I do the same operations from the CUPS web page.
      Code:
      E [19/Sep/2009:14:30:14 +0200] Pause-Printer: Unauthorized
E [19/Sep/2009:14:30:36 +0200] Resume-Printer: Unauthorized
      The access_log is OK. It's filled with a lot of "ok" and "successful":
      Code:
      localhost - - [19/Sep/2009:14:33:06 +0200] "GET /ppd/PSC1355.ppd HTTP/1.1" 200 20523 - -
localhost - - [19/Sep/2009:14:33:06 +0200] "POST / HTTP/1.1" 200 376 Get-Jobs successful-ok
localhost - - [19/Sep/2009:14:33:11 +0200] "POST /classes/ HTTP/1.1" 200 224 CUPS-Get-Classes successful-ok
localhost - - [19/Sep/2009:14:33:11 +0200] "GET /ppd/PSC1355.ppd HTTP/1.1" 200 20523 - -
localhost - - [19/Sep/2009:14:33:11 +0200] "POST / HTTP/1.1" 200 376 Get-Jobs successful-ok
      I also just discovered that actually none of the CUPS printers appear in KDE apps. There is a PDF "printer" setup in CUPS which does not show up either.

      Something strange with the CUPS setup after all maybe, even though printing works in other apps. Any more clues?

      This is my cupsd.conf:

      Code:
      LogLevel warning

      and my printers.conf:

        Re: Printer not visible in KDE apps

        Problem solved!

        As most often is the case, it was a simple problem. The wrong printing system was selected. To fix this I went into "Printers" under "System Settings" and selected "CUPS" at the "Print system currently used" drop down box.

        Thanks for taking the time to answer!

        Tobias
