print buffer produces incorrect format with emacs-22.1 and Sol 10

print buffer produces incorrect format with emacs-22.1 and Sol 10

[Gary Mills]

When `Print Buffer' is selected from the file menu, the file appears
on the printer, but some lines have extra spaces.  The letter `r' has
disappeared on these lines.  It's as if `pr -er | lp' has been used to
print the file.  Printing works correctly with emacs-21.2.

These differences in lpr.el appear relevant:

	< (defcustom lpr-page-header-switches '("-F")
	---
	> (defcustom lpr-page-header-switches '("-h %s" "-F")
	
	<                    (nconc (list "-h" title)
	<                           lpr-page-header-switches)))
	---
	>                    (mapcar (lambda (e) (format e title))
	>                            lpr-page-header-switches)))

So does the problem go away if you do:

(setq lpr-page-header-switches '("-F"))

I can't reproduce this though. Does it happen with every buffer? Can
you give a recipe starting from

emacs -q --no-site-file

that shows the problem?

See below.

My test has been `emacs /usr/pub/ascii', followed by `ESC-X
print-buffer'.  One thing I also noticed is that the page header looks
like this:

    Jun 11 11:25 2007    a Emacbuff Page 1

I replaced lpr.elc and lpr.el in /usr/local/share/emacs/22.1/lisp
with copies from emacs/21.2/lisp.  After that, the page header was:

     Jun 12 10:10 2007    ascii Emacs buffer Page 1

The rest of the file was correct too.

I was able to capture the file before it went to the printer.
My test was `emacs -q --no-site-file /usr/pub/ascii', followed by
`ESC-X print-buffer'.  Here's the beginning of the file:

Here's the same test after I did ``(setq lpr-page-header-switches '("-F"))'':

What do the header and first few lines of output look like when you
try on the command-line:

pr -h "ascii Emacs buffer" -F /usr/pub/ascii

and

pr -h ascii Emacs buffer -F /usr/pub/ascii

Not quite the same symptoms...

Can you confirm it works if you use this:

(setq lpr-page-header-switches '("-h" "%s" "-F"))

Yes, it works...

Okay, that was too simple!  The same peculiar thing happens on the
command line:

  $ pr "-h ascii Emacs buffer" -F /usr/pub/ascii | head

I'll have to go look at the source to see why it does that.  It makes
no sense at all to interpret some characters as flags and the rest
as the header.
