It is necessary that when you click on the button on the page, the document immediately goes to print.

this is a game, and thank the eggs that sane browsers do not allow this.
there is a standard way: window.print();and there the user himself decides what to do. for example, on OSX, instead of printing, you can save the page to pdf.
