I frequently have to print a 3-page document. Wanting to save paper, I print it 2-to-a-page, double-sided. So I end up with the front having "1 | 2", and the back having "3 | ".
It'd be more convenient if the front had " | 1", and the back had "2 | 3". Is there a way to have Mac OS X printing insert a blank page at the start when printing?
