I don't think we have any control over Report Preview Window.

Here is my wild guess.

1. Create a Timer Control. Let it fire every 100 milli seconds.
2. When printing starts, a small window pops up displaying progress of the pringing
3. Check to see if this window is up using WONTOP() function in the Timer() event.
4. If it was ever poped up, you know user printed the report.
