Cannot print to correct paper size - Canon iR-ADV C5051

Every time I try to print to 11x17 paper on a Canon iR-ADV C5051, the print job appears to go through, but when I get to the printer, it asks me to select a page size - and I select 11x17 and everything is fine.  This only happens when printing from DraftSight.  I can print the same file to an 11x17 PDF and then print from Adobe Reader or Acrobat to the same printer and paper size without issue.  No one else in my office has this problem.  What can be causing this and what is the fix?
