Re: Printing problems using Citrix Thread #677666 Message #679253

I think that it sounds like the below needs to be followed:

http://knowledgebase.citrix.com/SERVICESOFT/DATA/CITRIXKB/document/whitepapers/printing/icaprinting.pdf

It definitely sounds like a client configuration issue in the ICA client or the configuration of the local machine access via the ICA client... just guessing though...
