The JavaScript related to printing as shown on page 640 of the Adobe XML Form Object Model Reference does not work in Reader 8.0. I think the problem is that in Reader 8 there is a different page range in the Print Dialog Box. The previous version had 2 page range entry boxes - from and to. The new version has only one entry box in which you enter "from - to". Therefore the print JS using script xfa.host.print(1, "0", "0", 0, 1, 0, 0, 0); does not work. I have not been able to locate anything else that will work. Any ideas? Thank you.
The script...
xfa.host.print(1, 0, 0, 0, 1, 0, 0, 0);
should work just fine.
