When trying to print from Photos on my iMac (OS High Sierra 10.13.6), it is only printing a 2x4 print, even though I am changing the paper size and print size. I have no updates currently on my computer. Printer was reinstalled

Hi nonnydonna,

Thanks for contacting Apple Support Communities!

We understand that when you print photos to your printer form your Mac, they always turn out the same size.

If your printer supports Custom and Contact Sheet, you can resize the photos being printed before you print them as outlined here: Print your own photos in Photos on Mac - Apple Support

1. "In the Photos app  on your Mac, click Library in the sidebar, then select one or more photos.
2. Tip: To print multiple copies of the same photo on a single page, create as many duplicates of your photo as you need, then select them all before choosing File > Print. See Duplicate a photo.
3. Choose File > Print.
4. In the print options, select a format from the list on the right.

The preview area on the left shows the look of your printed photos.

With some formats, such as Custom and Contact Sheet, you can resize the printed photos. Other options, such as for repositioning photos, choosing an aspect ratio, or setting margins, appear depending on the format you select.

4. Choose a printer and select any necessary printer settings.

5. Click Print.

6. Specify print options in the Print dialog, then click Print."

We hope this helps.

Cheers!
