providing you have the optional finisher unit on the 3370, you should be able to store the set up of your most used printer settings.
You need to open up the docu centre screen, and select the 'page output' tab. Once clicked on this tab you should see towards the bottom on the RHS a folder type icon with 'saved settings'.
You'll be able to save you favourite settings to include papersizes, duplexing, finishing etc in your printer driver. I understand that you can select a specific printer preference as the default from there.
Hope that helps.
