-  If you want to use your local printer, printing on it in the usual DOS
-manner, then set the Lisp variable @code{lpr-command} to @code{""} (its
-default value) and @code{printer-name} to the name of the printer
-port---for example, @code{"PRN"}, the usual local printer port (that's
-the default), or @code{"LPT2"}, or @code{"COM1"} for a serial printer.
-You can also set @code{printer-name} to a file name, in which case
-``printed'' output is actually appended to that file.  If you set
-@code{printer-name} to @code{"NUL"}, printed output is silently
-discarded (sent to the system null device).

-  On MS-Windows, when the Windows network software is installed, you can
-also use a printer shared by another machine by setting
-@code{printer-name} to the UNC share name for that printer---for example,
-@code{"//joes_pc/hp4si"}.  (It doesn't matter whether you use forward
-slashes or backslashes here.)  To find out the names of shared printers,
-run the command @samp{net view} at a DOS command prompt to obtain a list
-of servers, and @samp{net view @var{server-name}} to see the names of printers
-(and directories) shared by that server.  Alternatively, click the

-which share their printers via the network.

-  If the printer doesn't appear in the output of @samp{net view}, or

-connect a local print port such as @code{"LPT2"} to the networked
-printer.  For example, typing @kbd{net use LPT2:
-\\joes_pc\hp4si}@footnote{
-Note that the @samp{net use} command requires the UNC share name to be
-typed with the Windows-style backslashes, while the value of
-@code{printer-name} can be set with either forward- or backslashes.}
-causes Windows to @dfn{capture} the LPT2 port and redirect the printed
-material to the printer connected to the machine @code{joes_pc}.
-After this command, setting @code{printer-name} to @code{"LPT2"}
-should produce the hardcopy on the networked printer.

-  If you set @code{printer-name} to a file name, it's best to use an
-absolute file name.  Emacs changes the working directory according to

-@findex print-region @r{(MS-DOS)}
-@vindex lpr-headers-switches @r{(MS-DOS)}
-  The commands @code{print-buffer} and @code{print-region} call the
-@code{pr} program, or use special switches to the @code{lpr} program, to
-produce headers on each printed page.  MS-DOS and MS-Windows don't
-normally have these programs, so by default, the variable
-@code{lpr-headers-switches} is set so that the requests to print page
-headers are silently ignored.  Thus, @code{print-buffer} and
-@code{print-region} produce the same output as @code{lpr-buffer} and
-@code{lpr-region}, respectively.  If you do have a suitable @code{pr}
-program (for example, from GNU Textutils), set
-@code{lpr-headers-switches} to @code{nil}; Emacs will then call
-@code{pr} to produce the page headers, and print the resulting output as
-specified by @code{printer-name}.

-  Finally, if you do have an @code{lpr} work-alike, you can set the
-variable @code{lpr-command} to @code{"lpr"}.  Then Emacs will use
-@code{lpr} for printing, as on other systems.  (If the name of the
-program isn't @code{lpr}, set @code{lpr-command} to specify where to
-find it.)  The variable @code{lpr-switches} has its standard meaning
-when @code{lpr-command} is not @code{""}.  If the variable
-@code{printer-name} has a string value, it is used as the value for the
-@code{-P} option to @code{lpr}, as on Unix.

-  A parallel set of variables, @code{ps-lpr-command},
-@code{ps-lpr-switches}, and @code{ps-printer-name} (@pxref{PostScript
-Variables,,,emacs, the Emacs Manual}), defines how PostScript files
-should be printed.  These variables are used in the same way as the
-corresponding variables described above for non-PostScript printing.
-Thus, the value of @code{ps-printer-name} is used as the name of the
-device (or file) to which PostScript output is sent, just as
-@code{printer-name} is used for non-PostScript printing.  (There are
-two distinct sets of variables in case you have two printers attached
-to two different ports, and only one of them is a PostScript printer.)
-
-  The default value of the variable @code{ps-lpr-command} is @code{""},
-which causes PostScript output to be sent to the printer port specified
-by @code{ps-printer-name}, but @code{ps-lpr-command} can also be set to
-the name of a program which will accept PostScript files.  Thus, if you
-have a non-PostScript printer, you can set this variable to the name of
-a PostScript interpreter program (such as Ghostscript).  Any switches
-that need to be passed to the interpreter program are specified using
-@code{ps-lpr-switches}.  (If the value of @code{ps-printer-name} is a
-string, it will be added to the list of switches as the value for the
-@code{-P} option.  This is probably only useful if you are using
-@code{lpr}, so when using an interpreter typically you would set
-@code{ps-printer-name} to something other than a string so it is
-ignored.)
-
-  For example, to use Ghostscript for printing on an Epson printer
-connected to the @samp{LPT2} port, put this in your @file{_emacs} file:
-
-@example
-(setq ps-printer-name t)  ; Ghostscript doesn't understand -P
-(setq ps-lpr-command "c:/gs/gs386")

-                        "-sOutputFile=LPT2"
-                        "-Ic:/gs"))
