I use GeckoFx to capture an image of a web page. The problem is that this web page has a script:

<script language = "JavaScript">
window.print (); window.close ();
</ script>

The above script opens a print dialog box and requires interactive user input to continue.

Question: How do I automate the process - for example say by stopping the dialog from opening.

Is there a way to disable the native javascript printing method (window.print)?

I already tried to inject a script into the html header:

window.print = function () {}

But this does not work. it inserts the script but the dialog box keeps showing up. (I do it in the DocumentCompleted event).

I found how to disable window.alert using PromptServiceCreator, but I can not disable window.print

I do not care about window.close because it does not run (firefox does not run it).

Why the vba tag please? – QHarr Oct 29 '18 at 08:38
you could try setting GeckoPreference "print.always_print_silent" to true. – Tom Oct 29 '18 at 16:58
If I use print.always_print_silent, the dialog box disappears but sends the printer to print by default that's not what I'm looking for, I need to disable the impression. – Rubén Aruzamén Oct 30 '18 at 02:20
A way that certainly works is to modify GeckoFx source directly, see the Print() method in GeckoWindow.cs. – wp78de Nov 05 '18 at 16:45
