Thanks Rick, I did find that the Win32_Printer WMI class has a property called EnableBIDI that is read/write. I was able to put together a short vbscript to accomplish this task. I also noticed that the prncnfg.vbs also includes this as well.

Hi Joe, The change has to be made programmatically with appropriate change notification. The best I can do to help is point you to Microsoft Technote How To Modify Printer Settings with the DocumentProperties() Function KB167345. This has a code example that should give you what you need. regards, Rick -- Ulrich Mack Commander Australia
