I found lots of advice on how to scale an A4 down to A5 and have two per A4 page. I have one A5 document that I want to print two copies of on an A4 page.
I don't think it's that relevant, because I believe in working toward a higher quality language, where you tell me what to do on "A printer", and I find its way of doing what you describe, but I'm using an Epson Stylus SX235W with MS-Word 2013.

Choose File -> Print. Select "Two page per sheet" and then press Print.
