Hi!
In our office we have a couple of cups-browsing announced network
printers, amongst those "mono at millbank". For some reason unknown to me
this was somehow duplicated as "mono at millbank@helen-x60".
(/etc/cups/printers.conf attached; this works with a default
cupsd.conf) Now this appears as one local printer, both with lpstat
and in the web interface:
$ lpstat -p
printer mono is idle. enabled since Sat Jul 19 11:42:18 2008
Now try to delete the printer, by either using lpadmin or the web UI:
$ lpadmin -x mono
D [19/Jul/2008:11:45:16 +0100] cupsdAuthorize: Authorized as root using
Local
D [19/Jul/2008:11:45:16 +0100] CUPS-Delete-Printer
ipp://localhost/printers/mono
D [19/Jul/2008:11:45:16 +0100] cupsdIsAuthorized: username="root"
I [19/Jul/2008:11:45:16 +0100] Saving subscriptions.conf...
I [19/Jul/2008:11:45:16 +0100] Printer "mono" deleted by "root".
I [19/Jul/2008:11:45:16 +0100] Saving subscriptions.conf...
I [19/Jul/2008:11:45:16 +0100] Saving printers.conf...
D [19/Jul/2008:11:45:16 +0100] cupsdProcessIPPRequest: 14 status_code=0
(successful-ok)
"lpstat -p" is empty now, as is the printer list in the web UI. But
despite the debug log above, printers.conf isn't changed, it still has
both printers.
Thus after "/etc/init.d/cups reload" it is back:
D [19/Jul/2008:12:00:19 +0100] Loading printer mono at millbank...
D [19/Jul/2008:12:00:19 +0100] Loading printer mono at millbank@helen-x60...
D [19/Jul/2008:12:00:19 +0100] Added implicit class "mono"...
$ LC_ALL=C lpstat -p
printer mono is idle. enabled since Sat Jul 19 12:00:19 2008
So cupsd gets horribly confused by these two: it treats them as one
printer, not two, with DeviceURI "file:///dev/null" (!), and it isn't
possible to delete the bogus "mono at millbank@helen-x60" printer.
