Using CUPS 1.1.17 with Samba.
From the CUPS GUI, there are the 'Location' and the 'Description'
fields. The 'Description' will be transferred to Windows property sheet
as the 'Comments' field but the 'Location' is NOT transferred to the 'Location'
field in Windows.
If there is any change made from the CUPS GUI about the 'Comment' field, that change is not populated to Samba. As a result, Samba only show the old 'Comment'.
One possible reason is that after driver is uploaded, Samba will
publish "PRINTERS/<printer name> part of the ntprinters.tdb file, while changing printer's comments through CUPS GUI referes to SECDESC/<printer name> part.
Fixed for Samba 3.0.25pre2
