I can print from the control in Delphi, although I've not tried doing it automatically when a page is loaded.
What version of the control are you using?
What exception are you getting?

I've looked everywhere but still haven't found a solution. My need is simple, I want to have the embeded Mozilla ActiveX control to print automatically when a document finished downloading.
So, what I did was to add a DocumentCompleted event to the Mozilla control:
private void axMozillaBrowser1_DocumentComplete (object sender, AxMOZILLACONTROLLib.DWebBrowserEvents2_DocumentCompleteEvent e) {
if (axMozillaBrowser1.ReadyState == MOZILLACONTROLLib.tagREADYSTATE.READYSTATE_COMPLETE && axMozillaBrowser1.Busy == false) {
MOZILLACONTROLLib.OLECMDID cdPrint = MOZILLACONTROLLib.OLECMDID.OLECMDID_PRINT;
MOZILLACONTROLLib.OLECMDEXECOPT cdDontPromptUser = MOZILLACONTROLLib.OLECMDEXECOPT.OLECMDEXECOPT_DONTPROMPTUSER;
object _null = null;
axMozillaBrowser1.ExecWB(cdPrint, cdDontPromptUser, ref _null, ref _null); }
}
As much as I wanted this to work, it doesn't. What I found out is, even when the document completed event is fire, the mozilla control is neither "complete" nor "not busy."
So, my next step is to add a while loop inside the document complete, hoping that when the readystate changed to complete and the control becomes not busy, it will print automatically.
It didn't work neither. I thought that it may be a threading issue. So, I make the while loop a separate thread.
This seemed to work better. But then, I found that a successful url change could lead to multiple document complete events. OK, so I added a routine to make sure only the first document complete events fire the thread to test the mozilla control's state.
This got me really close. Except that, when it actually printed, I got a COMException.
At this point, I gave up.
I would be really appreciate anyone who can give me a hand on how to solve this mystery.
