function [pcmd,dev] = printopt(varargin)

%PRINTOPT Printer defaults.

%	PRINTOPT is a MATLAB file that you or your system manager can

%	edit to indicate your default printer type and destination.

%

%	[PCMD,DEV] = PRINTOPT returns two strings, PCMD and DEV.

%	PCMD is a string containing the print command that

%	PRINT uses to spool a file to the printer. Its default is:

%

%	   Unix:      lpr -r

%	   Windows:   COPY /B LPT1:

%	   Macintosh: lpr -r (Mac OS X 10.2 and higher)

%                     Print -Mps (Mac OS X 10.1)

%

%   Note: Solaris users who do not use BSD printing, i.e. lpr,

%   need to  edit this file and uncomment the line to specify 'lp -c'.

%

%	DEV is a string containing the default device option for 

%	the PRINT command. Its default is:

%

%	   Unix:      -dps2

%	   Windows:   -dwin

%	   Macintosh: -dps2

% This file automatically defaults to the dev and pcmd shown above

% in the online help text. If you would like to set the dev or pcmd

% default to be different from those shown above, enter it after this

% paragraph.  For example, pcmd = 'lpr -s -r -Pfred' would change the 

% default for Unix systems to send output to a printer named fred.

% Note that pcmd is ignored by the Windows drivers.
