Printer issues using Citrix?

We have remote users using Citrix using CRM 4.0 for Outlook 2003. The CRM 4.0 Application is customized and connects to a sharepoint document library. When the user tries to print from the document library within CRM 4.0 the pages come out black. What could be causing this issue.

From serverfault

• Are you using the Citrix UPD (Universal Print Driver?)

• Seen this with HP drivers, see if you can swap between PCL5 and PCL6 driver. Also does this document happen to landscape?
