The samba logs show
[2009/09/07 00:50:53,  0] printing/print_cups.c:cups_connect(68)
  Unable to connect to CUPS server /var/run/cups/cups.sock:631 - No such file or directory

though none more recently.  I do shutdown cups nightly for a snapshot at
that time. I do not shut down samba.

Second, the packets seem to show the client trying to open \\Corn
\rawPrinter and the server replying
return code: File not found (pathname error) (0x0000002)

I am able to print to the printer from the client.
