Print selected pages

I'm using Run a Javascript to print pages 1 and 3 of a document using this code:

var x = this.getPrintParams();
x.printRange = [[0,0], [2,2]];
this.print(x);

It works, but it pops up the print dialog box first.  I'm wondering if there is a way to bypass the print dialog box and directly print pages 1 and 3.  Thanks.
