Printing from emacs

Printing from emacs

[Brian Poole]

When I select print buffer from the file menu I get the following error:

"Searching for program: no such file or directory, lpr"

How can I configure emacs to use lp instead of lpr?

Thanks

Though this is not really an answer to your question:
Consider using M-x ps-print-buffer.

Type C-h k, then click on "print buffer". You will get a description
of the command that has the information you need. In particular, see
`lpr-command'.

I changed lpr-command to lp.  When I select print-buffer now I get the
error message:
searching for program: success,

Why doesn't lpr-command execute lp?

Thanks

Is there more error message text?  What's at the end of the *Messages* buffer?


> Why doesn't lpr-command execute lp?

I don't know.  What happens if you do this:


C-x h
M-| lp RET

The message buffer prints out.

Please M-x toggle-debug-on-error RET, reproduce the above error
message, then show us the resulting backtrace.

It doesn't help you, but it helps us help you.

Debugger entered--Lisp error: (file-error "Searching for program"
"success" "")
  call-process-region(1 192 "" "/tmp/emacs5DAz26" t nil "-h" "*scratch*
  Emacs buffer") apply(call-process-region 1 192 "" t t nil ("-h"
  "*scratch* Emacs buffer")) print-region-1(1 192 nil t)
  print-buffer()
  call-interactively(print-buffer)

It seems it was searching for a program called "" (the empty
string).  Weird.

This backtrace appears to be a bit short.  As you can see, it invoked
print-region-1.  C-h f tells you it's defined in lpr.  So do M-x
load-library RET lpr.el RET (the .el part is important) and retry.  I
think this gives you a better backtrace.

Have a look in the source: M-x find-function RET print-region-1 RET.
Then search for "process".  This finds the following statement:

(apply 'call-process-region (car new-coords) (cdr new-coords)
		     lpr-page-header-program t t nil
		     (nconc (list "-h" title)
			    lpr-page-header-switches))

As you can see, it invokes lpr-page-header-program.  I'm guessing the
value of this variable is "", the empty string.

I got an error
cannot open load file lpr.el

Thanks for the help but I think I will just use the work around: M-x | lp

You need to install emac21-el.
