systemsettings and related printer issues in 22.04

re flag

In the process of debugging an issue with trying to print a test page, I found the following:

  • printing from all my various applications - graphics, office, etc, works fine under my non-privileged user id / normal user.
  • printing a test page from systemsettings run as normal user from menu fails with the "Unable to open print file: Permission denied" error, and printer itself hangs, apparently trying to print; however, printer ink levels are correctly displayed, and queue can be managed.
  • running systemsettings from the command line, as root, results in:
    1. much improved graphics in system settings (background is light, not dark, ink levels displayed more clearly, etc)
    2. printing the test page works fine

Since I have a workaround (running systemsettings from command line as root), this is currently non-critical, but it may be causing confusion for folks setting up printers then trying to create a test page.

I have just experienced this in kubuntu 22.04.01. I could print from applications but could not print a test page from System Settings - the print queue item showed "Unable to open print file: Permission denied".

Adding myself to group lp with sudo usermod -a -G lp <user> fixed it for me (I was already a member of lpadmin but not lp for some reason).

Thank you! yes, that resolved it for me as well. gui is better as root, for whatever reason, but functionally this resolved the issue. thanks again!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
