lpr options and printer names containing spaces

[Andrew Maguire (SWW)]

In GNU Emacs 20.7.2 (i386-*-nt4.0.1381)
 of Mon Nov 27 2000 on buffy
configured using `configure NT'

I have been playing around trying to get print-buffer to work with a printer
name that includes a space - Ugh!
(setq lpr-command "print")
(setq printer-name "\\\\network\\printer name")

It is caused by the subtle interactions between printer-name and
w32-quote-process-args
and perhaps a bug in the lpr code that should perhaps quote the printer-name
correctly
 (/D:"\\\\network\\printer name").

The results of my findings are as follows:

w32-quote-process-args has to be nil to prevent the printer-name being split
on each space.
I tried setting it to ?\" but although that returned the error from print:
Invalid switch - "/D:"\\network\printer name""
I could not see why it was invalid because it looked ok to me.

If I did (setq printer-name "\"\\\\network\\printer name\"") then the lpr
code did not recognise it as network printer name
and stuck c:\ in front of it.

I ultimately want call-process to look something like:
(call-process "print" nil " *print-region-helper*" nil
"/D:\"\\\\network\\printer name\"" "c:\temp\EB4564EC")
