RE: [h-e-w] ps-print duplex printing?

[Brown, Stephen D]

I tried setting the ps_spool-duplex variable, but it did not help.  An
additional comment in the ps-print.el source says:

;; Don't forget to set `ps-lpr-switches' to select duplex printing
;; for your printer.

I've tried setting the ps_lpr_switches variable but I get the error 
'Wrong type argument: listp, "&l1S"'

The value I'm trying to set the switch to is "<ESC>&l1S", but I'm not sure
how to put the escape character in the value.  I'm not even sure that would
work, but I would at least like to give it a try.

Hi,

Have you tried setting ps-spool-duplex to t?  Here's what the documentation
says:

-----8<-----
*Non-nil generates PostScript for a two-sided printer.
For a duplex printer, the `ps-spool-*' and `ps-print-*' commands will insert
blank pages as needed between print jobs so that the next buffer printed
will
start on the right page.  Also, if headers are turned on, the headers will
be
reversed on duplex printers so that the page numbers fall to the left on
even-numbered pages.

See also `ps-spool-tumble'.

You can customize this variable.

Defined in `ps-print'.
-----8<-----

For me this works on Postscript printers (currently a Xerox Document Centre
230) from ntemacs 21.2.1 ("GNU Emacs 21.2.1 (i386-msvc-nt5.0.2195) of
2002-03-19 on buffy" according to emacs-version) under W2K.  You could also
try letting ghostscript handle the printing.  I haven't tried that (except
by
opening the postscript file in gsview and print from there).

Hope this helps.

Cheers,
Karel

I'm using NT Emacs 20.7.1 on Win2K, and I'm trying to use the duplex
printing option for my printer.

At first I tried to just set up the printer driver to default to printing
both sides, but that did not work when I printed from emacs.
I then found the PCL Printer Command escape sequence for duplex printing on
my printer, but I don't know how to pass those parameters using Emacs. 

Can someone tell how to pass these esacpe sequences using Emacs, or am I
going about this the wrong way?
