#<buffer *scratch*>

"GNU Emacs 21.3.1 (i386-pc-linux-gnu)
 of 2004-10-16 on raven, modified by Debian"

(progn

; works fine printing this scratch buffer

(progn
  (setq ps-selected-pages '(1))
  (set-buffer "*info*") ; info buffer - emacs (Top)
  (ps-print-buffer nil))

; doesn't work - printer gears up and then winds down without doing anything
; spooled PS file ends up in /var/spool/cups/

; As you can see there are several failed print jobs here.
; I only use the *info* buffer as an example.  Behaviour is
; completely erratic as far as I can tell, but generally,
; individual pages and ranges are far more likely to fail
; that printing the whole buffer.  I have got some ranges
; to work by expanding the range beyond my requirements and
; then getting the range I'm after.
