How do you print photos from 2 different albums together on same page?

Another method is to put both of them into a temporary album, then select both and print. In the Print window select a print size small enough so both will print on one page.

Then delete the temporary album when done.

Hi

From photos - put them both temporarily in a third library (eg called print) (you can have the same photo in multiple libraries), and select them both for printing from there.

Or alternatively put them in a pages document and print from pages.

Use the All Library view so that you can Click one to select it, and Command-Click the second to select it without unselecting the first one. (I assume they are relatively close together in time so you don't have to hunt too far.
