Here's a workaround that may do the trick...

You can change turn off the print preview from within a file called "print.ini" on the Client side. Look for the file in:

C:\Documents and Settings\<username>\Local Settings\Application Data\print.ini (in XP)
C:\Users\<username>\AppData\Local (in VISTA)
or do a search from the CMD prompt.

Make a backup copy of the original "print.ini" file and then edit in notepad. Look for the PreviewState parameter near the top and change it accordingly.

PreviewState= 0900000009 ( Turn Print Preview OFF) 
PreviewState=0500000005 (Turn Print Preview ON)

Don't make any other changes to this file as you can corrupt this file.
