Windows Server 2008 x64 print server with x32 clients

Hope someone can help me.

Im replacing a x32 print server with a x64 as mentioned in the subject:

During the installation of pdfcreator I have selected "server installation" and also added 2000/xp/2003 x32 drivers

I have shared the PDFCreator printer for everyone, but under sharing and add. drivers only x64 bits are selected and If I choose x32 im asked for a location of the drivers.

If I go to the client and try to connect to the pdfcreator printer Im asked for a driver.

Any suggestions , any help appreciated.
