Log Message:
-----------
Howard Hoagland. Changed to use Jim Gabriel's new PCLPrintJob class, which meant to remove the PCL Direct printing and Windows Printing code in PosPrintPages, but keep the building of all the PCL bytes, so that the whole print operation is handled in PCLPrintJob with it's API being the initializePrintJob parameters. Implemented print duplex for Windows Print. Fixed bug when printing two pages, and doing Letter first then Legal, the two pages wouldn't reorder.
