browser - "Silent" Printing in a Web Application

Question

I'm working on a web application that needs to prints silently -- that is without user involvement. What's the best way to accomplish this? It doesn't like it can be done with strictly with Javascript, nor Flash and/or AIR. The closest I've seen involves a Java applet.

I can understand why it would a Bad Idea for just any website to be able to do this. This specific instance is for an internal application, and it's perfectly acceptable if the user needs to add the URL to a trusted site list, install an addon, etc.

Here’s what you need to do to enable Firefox immediately print without showing the print preferences dialog box.

1. Type about:config at Firefox’s location bar and hit Enter.

2. Right click at anywhere on the page and select New > Boolean

3. Enter the preference name as print.always_print_silent and click OK.
