Should really be that easy :-)

I have 2 reasons why I'm not using a simple script like the above for years:

1st, the add_printer_hook is called by a "update_printer" function.
This function is called really frequently.
Using an add printer command and not commenting this line out of the 
samba code slowed down everything in a massive way.

2nd, (and the true reason) - the add printer command is not really 
functional without port handling.

E.g. CUPS wants a device uri like "socket://192.168.3.100:9100" to know 
the destination of the printjob.
You could use the "location" or "description" in the add printer wizard 
as a workaround. But that's not really a nice way.
So to make your "lpadmin option1 ..." line really functional, you'll 
also need an "enumports comand" and the ability to create new ports and 
keep them in sync with the cups printers.

bye,

Martin
