I seem to recall that this is a known bug and that basically you're SOL.

Altough, come to think of it, it may actually have to do with print drivers. If the default printer/print driver is not exactly the same as your development machine, the 100% may be the only one available.

I used to tell my users, "Hey, what do you want? Perfect Function or Perfect GUI?" Depending on what the desire of the users are, you may want to consider a text viewer for on-line viewing of reports.
