On Tiger, we added "virtual printer" to cups, for internal use by our
application. We created a script in /usr/libexec/cups/backend/, copied
a PPD to /private/etc/cups/ppd/ and
updated /private/etc/cups/printers.conf. Once the printer is added, we
select & control it with lpoptions, lpadmin, lpstat, etc.
How are you updating printers.conf?
In general, manipulating printers.conf directly is a bad idea and
is highly dependent on the version of Mac OS X or CUPS you are
using...
Unfortunately, none of this works on Leopard. The cups operations are
all successful and internally consistent, but none of the changes are
propagated to the GUI/application level. Selecting & querying the
current printer can be performed using AppleScript on "Printer Setup
Utility", but I haven't figured out how to programatically add a printer
(particularly with a cups backend). Is there a recommended way to add a
CUPS printer on Leopard? Is there a way to sync the cups configuration
into the configuration used by the print dialog & system preference?
Either use lpadmin or the CUPS API with the CUPS_ADD_PRINTER
operation (the lpadmin source code should provide a good source of
inspiration for the latter...)
