App.execMenuItem("Print") Not Working in Reader 9.1

Question

All
I have a 15 page PDF form with a print button that leverages the following line of Javascript to invoke Reader's printing menu option:
app.execMenuItem("Print");
In prior version fo reader (7, 8 and even 9.0) this works properly. However, now in 9.1, I receive a dialog when I try to print stating that no pages were selected to print. This only occurs in 9.1.
Did something change with the printing capabilities with the 9.1 reader release? If so, how can I achieve this functionality?
Thanks

Hi,
In LC Designer, there is a standard script in the Print button:
xfa.host.print(1, "0", (xfa.host.numPages -1).toString(), 0, 0, 0, 0, 0);
The second parameter tells Acrobat the start page and the third parameter sets the last page to be printed (both are based on a zero page numbering system). The help file sets out the different parameters.
In AcroForms the following should print:
this.print({nStart: 0, nEnd: 7, bShrinkToFit: true});
Good luck,
Niall
