How do print multiple photos on one page?

To print multiple photos of a specified size on one page do the following;

1 - select the photos you want on the page and hit ⌘+P (print).

2 - in Photos' Print window select Custom option - #1

3 - at the top of the window select the paper size - #2

3 - at the bottom of the page select the image size to be printed - #3

Note: if the print sizes will fit on the page you'll see all three images in the left hand pane.
