Not directly but you can create variable llPrinted in your program and set it to .T. in the report

* Report Summary band on Exit. 
_VFP.SetVar("llPrinted", WEXISTS("Printing..."))

* Program 
llPrinted = .F.
Report Form myreport to Printer Promp Preview
IF llPrinted 
   ...
ENDIF

This way you can also capture situation when user cancels in the middle of printing.
