Re: postscript printing in emacs

[Rami A <rami.ammari@gmail.com>]

Hi again Pete,
Thanks for your response.

I am honestly not so proficient in emacs nor lisp.
I simply want the same format that 
mp -l -s "\!*" <\!* | lp 
produces when used on the command line integrated from within emacs.

I tried this:
(setq ps-lpr-command "mp")
(setq ps-lpr-switches '("-l" " -s" " | lp"))

which also did not work.

It is not that I want to use the pipe "| lp" but I just want to duplicate the same functionality to print the same kind of format.

GNU Emacs seems to search for an executable file name with SPACEs and VERTICAL BAR (|). AFAIR mp allows to specify with -D or -P a printer queue to which its output is being sent. Why can't you use mp without ' | lpr'? And why aren't you experimenting in GNU Emacs with its own customisation interface? It allows to apply new settings just for this session – and to revert them! If a combination of settings finally works well you can save them, from each of the open *customisation* buffers, into your init file.
