Bug description:
From CUPS 1.6.x on (Quantal) CUPS does not broadcast shared printers
any more using its own method, leading to the fact that clients do not
discover and make available printers on remote CUPS servers
automatically any more. Now one has to explicitly add the printer on
the client. To allow at least discovery of the server's printers, the
server broadcasts the printer information via DNS-SD/Bonjour (using
the Avahi daemon). Creating a queue on the client based on these
broadcasts is easy, system-config-printer shows the server's host name
under the discovered network printers and choosing this allows to use
the shared CUPS printer. On the client we then have a raw queue (no
local PPD/driver, we use the server's one) with a device URI like
this:
dnssd://Color%20Laser%20Printer%20%40%20server._ipp._tcp.local/cups
One can print on this printer via the "lpr" command and one can
display the options (defined in the PPD file on the server) with
"lpoptions -l".
If one opens the GTK print dialog (for example in evince), the printer
gets listed but it says "Getting printer information ..." infinitely
and the "Print" button stays grayed out, making printing through the
GTK dialog impossible.
This is a najor problem as it prevents printing on printers shared
between computers running Quantal.
The fix is simple and the debdiff is attached.
To reproduce: Take two Quantal machines, both need to run CUPS and
Avahi, the client needs to run a desktop and have GTK applicatiuons
installed. On the server create a print queue with system-config-
printer or by simply plugging in a USB printer, do not create a raw
(driverless) print queue. Share the printer ("cupsctl --share-
printers" or "Server"/"Settings" in system-config-printer). On the
client create a queue pointing to this printer, in system-config-
printer click the "Add" button and in the printer setup wizard wait
for the spinning icon to disappear, under the network printers choose
the host name of the server and complete the wizard, you will not get
asked for make, model, or driver. You will be able to print a test
page and to browse the printer's options with system-config-printer.
You also will be able to print from the command line or from KDE
applications. If you try to print from GTK applications the queue
displays in the dialog but is stuck with grayed "Print" button and
"Getting printer information ...".
