You can only do this if your CUPS version is sufficiently new.
Check by reading "man cupsaddsma". Does it already relate to the
CUPS PostScript drivers?

Which version of Samba and CUPS are you using?

You might need to restart Samba to get it to work (if you have the printer
"Canon_BJC", or any other, newly installed).

If this doesn't help, let root do a

    "smbcontrol smbd debug 3"

and then watch

    "tail -f /var/log/samba/log.smbd"    (or appropriate path)

while you try to connect to Samba from XP.

Make sure the connection is as a user who can write to the [print$] share.
Check which user you are from Samba's point of view, by asking for

    "smbstatus"

If you had unfortunately been connected as "nobody" (or another user with
a less priviledge account), kill all connections. But that is not enough:
you need to also close all Explorer windows on the client and connect *as
first thing* via a "DOS window":

   "net use \\sambaserver\print$ /user:root"

(instead of root, you could use a username priviledged enough to write to
the print$ share).

The problem is a bug on MS Win: they seem to cache info they received
previously from Samba (or a Win NT printer server) for as long as the
Explorer is open, and keep repeating the same message about "unavailable
driver files" without even asking again the Samba server for an update...
