[Samba] Printing to /dev/null ?

[samba at vaag.nu]

Hi list!

I need a Samba printer that will route all printjobs to /dev/null
(We have accounting software that requires every invoice to be printed 
before it can be booked and the invoice data is imported from other 
software so it's just wasting paper).

I tried creating a printer in cups with a printer URI of /dev/null but 
that doesn't work, the print jobs are just piling up and never disappear.

Anyone know a solution for such an unusual printer in Samba?

Thanks!
