Print Problem using AXWebBrowser

[AH]

Hi,

I am trying to print a document from an instance of IE and then
destroy the instance after the printing has completed.

I use the following code to navigate to the page.

object o = null;
axWebBrowser.Navigate(someurl, ref o, ref o, ref o, ref o);

I then use the DownloadComplete event when the navigation is finished
and I start the printing

object o = null;
axWebBrowser.ExecWB(SHDocVw.OLECMDID.OLECMDID_PRIN T,
SHDocVw.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER ,ref o, ref o);

Is there a way to determine if the document has completed printing??
I would like to know when I can destroy the IE instance and how??

Thanks!
AH
