win.print will only print the parent window

[aam-git]

NWJS Version : 0.44.1
Operating System : win-x64

Expected behavior

When I call the function below, the child window should print silently

Actual behavior

When I call the function below, the parent window prints not the child.

How to reproduce

const nwPrint = (data) => {

	nw.Window.open(`data:text/html,${encodeURI(data)}`, {focus: true}, (new_window) => {

		new_window.on('loaded', () => {

			new_window.print({
				"printer":"ZDesigner GK420d",
				"autoprint": true,
				"marginsType": 1,
				"headerFooterEnabled": false,
				"shouldPrintBackgrounds": false,
				"landscape": false,
				"mediaSize":{'name': 'CUSTOM', 'width_microns': 100000, 'height_microns': 150000, 'custom_display_name':'4x6 label', 'is_default': true},
				"preview": false
			});

		});
		
	});

}

nwPrint('Hello World');

I've tried every which way I can think of for the past few hours to make it print the child window, but its not letting me, each time I successfully mange to print, the parent window comes out.

Just tried it on multiple versions to try and work out where the change happened

Works fine on v0.39.3
Works fine on v0.40.2
Works fine on v0.41.3
Works fine on v0.42.0
Works fine on v0.42.2
Works fine on v0.42.3
Fails on v0.42.4
Fails on v0.42.6
Fails on v0.44.1

Looks like it has something to do with NW2 Mode in that case maybe?

I have the same issue.

If you disable the nw2 Feature in your package.json :
{
"chromium-args": "--disable-features=nw2",
}

the print will work perfect.

In issue #7230 Roger Wang ask for blocking nw1 removel issue.
I think this issue is one.

@rogerwang
Is it possible to reproduce this issue, or do you need further information ?

This is fixed in git and will be available in the next nightly build.
