Log Message:
-----------
Howard Hoagland. Added class PriModifyPclBytes and changed class PosPrintPages for when printing PCL Direct, parse the PCL and remove form feeds (to not get blank pages), remove printer reset commands (ESC E), remove page size, remove paper source tray or manual feed, remove number of copies, remove duplex
