Hello katesvobodaspanbock,
Thank you for reaching out to Apple Support Communities.
Let's review these settings:
"Print a document upside down
If you’re trying to print on material that you can’t insert into your printer in the direction you want, you can insert it in the opposite direction and then print your document upside down. For example, you can use this method to print on an envelope that won’t fit into the printer top first, or to print on unusually shaped paper.
- With a document open on your Mac, choose File > Print.
- If you see a Show Details button, click it to show more print options.
- Click the print options pop-up menu (at the top of the light gray box), then choose Layout."

If the issue persists, can you provide a few more details? When did you first notice this? Also, what is your exact macOS version?
Cheers!
