Remote Desktop sessions varying speed opening database reports

Windows Server 2008R2 with remote desktop services role (terminal services) and Access database

We recently had a user notice that database reports would open up at different speeds in different remote desktop sessions. After trying many different things, it was determined that printer redirection was causing some sessions to open database reports more slowly than others and the reports would open much faster if printer redirection was unchecked under local resources when making the remote desktop connection.
