Questions about ps print

Questions about ps print

[Rodolfo Medina]

It sometimes happens that in the ps file (that I get with `M-x pr-interface')
a blank page is added, although the bottom margin is set as 0.

Can anybody suggest why this happens and how to avoid it?

Thanks for any reply
Rodolfo

It might contain all the white space below your black text! You can  
customise the fringes to indicate the buffer boundaries and also to  
indicate the empty lines at the buffer's end.

Did you check in GNU Emacs the PS output to see what exactly is  
printed on that last empty page?

Can you indicate what variables shall I customize?

How can I do that?

Thanks indeed,

(custom-set-variables
   ;; custom-set-variables was added by Custom.
   ;; If you edit it by hand, you could mess it up, so be careful.
   ;; Your init file should contain only one such instance.
   ;; If there is more than one, they won't work right.
;; '(fringe-indicators (quote right) nil (fringe))
; '(fringe-mode (quote (3 . 7)) nil (fringe))   ; thickness of  
fringes left . right
  '(indicate-buffer-boundaries (quote right))    ; where is text  
indicated
  '(indicate-empty-lines t)                      ; with small  
horizontal lines
)

An example for colour use in the fringe:

(custom-set-faces
   ;; custom-set-faces was added by Custom.
   ;; If you edit it by hand, you could mess it up, so be careful.
   ;; Your init file should contain only one such instance.
   ;; If there is more than one, they won't work right.
  '(fringe ((((class color) (background light)) (:background  
"khaki" :foreground "steel blue"))))
)

You can also look-up the variable names and follow their hyperlinks  
to the customisation interface.

Only spool the PS print-out (M-x ps-spool-buffer-with-faces). It will  
create a buffer *PostScript*. It will contain words like "%%Page:  
<number> <number>" and "EndPage" that describe one page of output.  
Text output in PostScript is kept between "(" and ")" and followed by  
"S" and only in case of PS print output of GNU Emacs.

Thanks to Peter for his indications, however the problem seems to be solved
decreasing the value of the ps-footer-offset variable; although I can't
imagine what the distance between the main text and the footer has to do with
outputting a final blank page.

Make a bug report from this! Help menu -> Send Bug Report… Maybe  
there *is* some mis-conception no-one has thought of yet.
