[STR New]

On the HP LaserJet 5SI/MX, you can enable duplexing by default on the
printer itself. This sets the default mode if no other duplexing
instructions are sent. This is very useful when communicating directly
with the printer.

However, when you want to disable duplexing, CUPS should send a command to
explicitly set the value to OFF when not wanted. This is a patch to modify
rastertohp.c to do just that.

Note: This should be tested on other printer models to verify it does not
create problems. It works great on my printer--the page per minute speed
jumps through the roof when the paper bypasses the duplexing mechanism!
