[reportlab-users] Printing Help

When I try os.system(), it blocks on it.  One of my fundamental problems is that Acrobat refuses to start, print, and exit.  It wants to stay running, thus I have to detach to keep processing.  New Acrobat instances seem to send their requests to the original running process.

Best Regards,
