function bool = blt( pj, h )

%BLT Returns FALSE if Lines and Text objects in Figure should be printed in black.

%   Copyright 1984-2014 The MathWorks, Inc.

%DriverColorSet was turned to TRUE iff there was a device cmd line argument

%If there was a cmd line device argument we use the DriverColor resulting from it

%

%Otherwise we look for a PrintTemplate object in the Figure

%If there is one we return its DriverColor boolean value.

%

%Otherwise, on windows, 

% 1. if we're printing from the dialog (pj.Verbose) we

%    return true (and let the print code determine later if we need to change

%    to b&w)

% 2. if we're not printing from the dialog we base decision on whether or

%    not the printer supports color 

%

% Otherwise we just look at the driver and whether it says it supports color 

% (pj.DriverColor)

%depviewer should always be printed in color mode to avoid

%the going through NODITHER
