Log Message:
-----------
Howard Hoagland. Put in more code to fix the duplexing to force back pages to be front pages when the DSP info in a Blockument says that form is "Duplex=No" and also force to a front page all Page 1's of forms. Fixed the problem of pages that were supposed to print on the back side were going to the front of the next page, by sending the page size commands to the printer only if the page size changed, and not at the start of every page.
