Hung up on print

Environment: Delphi 7   Windows 2003 Server  QuickPDF 725

My application uses:

  function TQuickPDF0725.PrintDocument

The document prints, however, my application hangs for a full 32 seconds once this command is called.  The printed document is exiting from the printer long before the function "lets go" of the thread and my app starts working again.  No other application that prints displays this behavior.

My understanding is that the PrintDocument should just hand the print job off to the print spooler (2 seconds maybe) then carry on.  Is there something I'm missing here, or is there a work around or update that solves this problem?  Thanks for any help you can provide.
