Windows Server 2008 Remote Desktop printing blank pages

I have a Windows Server 2008 (not R2) machine which has problems with redirected printing.

Clients connecting via Remote Desktop have their printers redirected and appearing for them to print to, but printing from applications on the server to local printers is giving blank pages, missing pages, or pages with headers/footers but no middle section. The issues are consistant for similar prints, but sometimes other prints and/or applications will work correctly.

I have installed PDFCreator locally on the server, and the same print jobs sent by the same application appear correctly in the PDFs. Printing that PDF via the redirected printer prints correctly.

I have tried the following:

1. Installing drivers. I’ve installed several drivers different drivers, for both the client and server operating system and architecture, on the client and the server.
2. Reinstalling the printers. I’ve tried reinstalling on remote print servers, the clients, and the host server, and tried different client machines.
3. Granting everyone full permissions on the print spool folder on the server.
4. Editing the registry to forward non-USB ports (http://support.microsoft.com/kb/302361)

None of these have made any difference.

The clients are using Windows 7 or Windows XP and none of them have any issues with printing locally.

Any ideas?

Thanks!
