Have you got ANY word processor (such as OpenOffice Writer)? The instructions above should still work. (If you've not got OpenOffice, you might care to download and install it. It's free and just as good as Microsoft Office:

I'd also expect those instructions to work in any DTP program, such as Microsoft Publisher or PagePlus Starter Edition. (It's free and well worth having on your computer):

With a word processor you'd probably need to place one photo under another. (i.e. import one photo, press the 'Return' key a few times to move down by a few lines and then import the second picture). With a DTP program you can put the pictures wherever you like on the page.
However I'm surprised that your printer didn't come with specialist software for printing photos exactly how you want them to appear on a page. (With Canon printers it's called Easy-PhotoPrint). Take a look at what's already on your computer.
