KDe FC6 64, printer keeps disabling itself
I am running KDE FC6 64 bit. I have a canon pixima printer connected by TCP and works well. The small problem we have is everynow and then it disables itself in the KDE/Configure Printers menu.
Under KDE I go Printing/Configure Printers, then enter root password. This the brings up the Printer Configuration Dialog. On the left hand side half way down it has a Title: State. This has 3 tick boxes Enabled, Accepting Jobs, Shared. These are all ticked.
Every couple of days a user will go to print and nothing happens. If you goto Printing/Configure Printers you will see no tick under State: Enabled. Clicking on the tick box for Enabled and Applying makes everything fine again.
I have no idea how this disables itself if only root can enable or disable it.
This has been happening for the last couple of months but have a chance to try and spend some time on the little annoyings things happening in my distro.
Look forward to any help you can give me on this.
