[Tutor] Problem Automating Internet Explorer Printing

[Jeff Peery]

Hello,
I'm using the code pasted below to print a document. The code worked great on my XP machine. I moved it to my W7 machine and it gives the error below. The weird thing is that it works great if printing a html doc from the web (such as www.google.com), but it errors when printing a html doc from my desktop. The document loads as I can see it on the screen, but it chokes when printing.
any ideas?
thanks,
Jeff
