The printing process works ok for me (Win 7, 64 bit).
I suggest trying the following...
1. Return to factory settings and restart BIAB for the settings to load.
2. If the problem persists, download update 431 (
from here) and install it. This will take BIAB back to the previous update (which I'm assuming was working).
This way, you shouldn't be disadvantaged in relation to printing music while PG Music tweak build 432.
