[Samba] Win2K. Raw CUPS printing, driver download

A little more information:

I did some extensive googling and found at least two other
(unresolved) reports of the same problem, with different printers.  In
March, somebody named "Zylo" reported this with a Canon multifunction
device, not using CUPS:
The only response was Rainer Janson reporting the same problem with
"all Canon image-runner-systems with canon ps drivers installed via
point and print".

I think this establishes this as a Samba bug.  It happens with
different spoolers, different printers, different distros, and
different drivers.  Samba is the only common factor.

The line on the first page begins like this:

@ ASCII-128 \\my-server\my-printer smiley diamond square

and ends like this:

smiley \\my-server\my-printer part-of-my-document-name

(The ASCII-128 character looks like a capital C with a tail)

Oddly the first letter of the server name is lowercase the first time
and uppercase the second time, but the first letter of the printer
name is upper case both times.

I'm beginning to think that Samba doesn't handle some behavior which
only a small number of Windows drivers have.  I wonder if this might
be a case-sensitivity issue, or maybe a CR vs CR-LF issue.

So far the only workaround I've found is to install the printer as
local on the Windows machine, then add a "local" port named
\\server\printer and set the printer to that port.  Unfortunately that
makes the form of printer name different in printer selection dialogs
than all the other printers shared by Samba.
