Wyse Xenith, XenApp 6, and Lexmark printers

Wyse Xenith, XenApp 6, and Lexmark printers

I am having a problem with Xenith clients and XenApp 6. Specifically, I am attaching a Lexmark 250d printer to a Wyse Xenith client but when I connect to the XenApp 6 desktop, I do not see the printer mapping in the Citrix application. That's fine and all, but I can't troubleshoot it either because there is nothing in the event log in regards to a Citrix error. Citrix is not even trying to map the printer because it does not see that it is there, thus no event log warning or error is issued. The zero client detects when I plug it in so as far as I can tell, the zero client sees it.

When I plug this printer up to my laptop, my laptop sees the printer and then when I login to Citrix, Citrix maps the printer just fine. So I guess my question is, why won't the printer map when it's connected to the zero client? What's the disconnect between Wyse and XenApp? Other printers, like HP DeskJet and stuff have worked just fine. I have only seen this issue when trying to use the Lexmark 250d.

Any assistance would be greatly appreciated.
