Hallo dear George,
Recently we had some problem related to the mapping over Citrix Cognos of the "local" printer present over user PC.
Then we have activate one Citrix Policy that map only the default printer set over user PC.
By the way is mapped just one printer during connection.
The please chose win2pdf as default printer before connect to Cognos.
This is a workaround temporary, but actually there is any other way.
We keep update for the news...
Thanks BR.
