Many people aren't aware that most printers have the ability to print two or more pages on one sheet of paper. Each page (or image) is made smaller, so they will fit side-by-side, or one-over-the-other, on a sheet. Although every printer is a little different, most will have the following options:
When you choose to 'Print' something, a window appears to give you many options that include: number of copies, specific pages to print, whether to collate the pages, whether to scale/fit to the paper size, and Pages per sheet. The default setting is one page per sheet of paper, as indicated by the '1 page' on the bottom right.
If you choose 2 pages - or more - your printer will automatically size the pages so that 2 or more pages will print on one sheet. My printer has the option to print as many as 16 pages per sheet - making each page the size of a postage stamp. The ideal, of course, is to print 2 pages per sheet. This retains a readable text size, while saving paper and ink.
