Hardcopy Output
===============

   The Emacs commands for making hardcopy let you print either an entire
buffer or just part of one, either with or without page headers.  See
also the hardcopy commands of Dired (Note: Misc File Ops) and the
diary (Note: Diary Commands).

`M-x print-buffer'
     Print hardcopy of current buffer with page headings containing the
     file name and page number.

`M-x lpr-buffer'
     Print hardcopy of current buffer without page headings.

`M-x print-region'
     Like `print-buffer' but print only the current region.

`M-x lpr-region'
     Like `lpr-buffer' but print only the current region.

   The hardcopy commands (aside from the Postscript commands) pass extra
switches to the `lpr' program based on the value of the variable
`lpr-switches'.  Its value should be a list of strings, each string an
option starting with `-'.  For example, to specify a line width of 80
columns for all the printing you do in Emacs, set `lpr-switches' like
this:

     (setq lpr-switches '("-w80"))

   You can specify the printer to use by setting the variable
`printer-name'.

   The variable `lpr-command' specifies the name of the printer program
to run; the default value depends on your operating system type.  On
most systems, the default is `"lpr"'.  The variable
`lpr-headers-switches' similarly specifies the extra switches to use to
make page headers.  The variable `lpr-add-switches' controls whether to
supply `-T' and `-J' options (suitable for `lpr') to the printer
program: `nil' means don't add them.  `lpr-add-switches' should be
`nil' if your printer program is not compatible with `lpr'.
