I'm a newbie with JavaScript and I was looking for a method to print a pdf document with a button click without any dialog window opening or not make the user able to change the print settings, I want to print it with a fixed printer, number of pages and format.
I already tried Print.js but it still opens a dialog window and the user can change the settings in it.
The browser does not allow it to print automatically without the user being able to choose the settings to print. This would be extremely problematic as someone can print endless pages without the users permission
