Hello David Menges,
If you have not already resolved this issue, we suggest you search our online knowledgebase for this product: WorkCentre 5665.
Alternatively, you can visit our Contact Us page for other support options.
We have a laptop whose owner wants to print to a local WorkCentre 5665 during a Citrix session that requires a PostScript driver. She already has a PCL driver installed and uses that locally fine.
I see a WorkCentre 5665 PS driver 184.108.40.206, which says it is supported in Citrix environments, but it is not obvious how to install it - it's just a bunch of .dlls, etc.
Or should I just be using Xerox's Global Print Driver?
