Re: Adding a printer programatically in Leopard

Michael,

I've replaced my edit to printers.conf with a call to lpadmin, and it resolved my issue.

Thanks,

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...)
