How to set the number of copies to print from javascript [duplicate]

Answer 1

It is not possible, one solution would be to call the print twice

window.frames["doc1"].focus();
window.frames["doc1"].print();
window.frames["doc1"].focus();
window.frames["doc1"].print();

Answer 2

There are no additional parameters for the window.print() method and definitely no parameter that allows you to specify the default number of copies.

The only workaround for this that I can think of would be to call the print() method twice on doc2. Obviously not the greatest user experience.
