[Bug 44465] Re: can't add printer, consumes 100% CPU

[Kevin Knerr]

I can confirm this behavior, although I seem to have found a fix.

I had previously set up my Epson Stylus C86 and it was working
correctly. When I went to print yesterday, I got no output. After
verifying ink levels, cleaning the heads, replacing two cartridges, and
cleaning heads again. I decided to remove and add the printer driver
again, given the recent number of cups updates for Dapper. I received
exactly the same behavior described above.

Interestingly enough, after adding user cupsys to the shadow group and
restarting the cups daemon,  the CPU usage was pinned very briefly and I
was able to add a printer successfully via gnome-cups-manager.

It would seem that disabling printer administration from the
http://localhost:631 interface also disables administration via the
GNOME GUI.
