1, the use of the scene
The user prints a small ticket automatically after doing something in the browser.
2, test methods
2.1 JavaScript implementation
Tried a lot of ways, eventually will appear a pop-up box, let the user select the printer. Not in line with our needs.
2.2 Lodop
The function is more powerful, but the charge. No consideration.
2.3 Pazu
The function is also very powerful, free license. It's awesome!
