Can I change the paper size in my DeskJet?

[Random_Dinosaur]

So I got this packet of 10x13cm sticky backed photo sheets with my printer and I can't work out if I can print on them. Have I missed something? If anyone can let me know if it's possible for me to print on them and how I'd much appreciate it, thanks for taking the time to read this and maybe even help me!

I would guess that the paper is "Social Media Snapshots Paper".

If that is the case, it appears the photos are printed from an "app" from Apple or Google.

The Specifications indicate the 4x5" paper size is not a supported (standard) size.  The how-to instructions (below) explain that you can adjust the expected Paper Size to "Custom" in the Embedded Web Server (EWS) to accommodate the size.

Open EWS

Open your favorite browser > type / enter Printer IP address into URL / Address bar

Open the print instructions in the app to view and set the print settings (step 2), including the paper size and paper type (photo paper).

These little photo papers are "sunlight" sensitive.  Display / store photos printed on this paper away from direct sunlight to help preserve the image on the paper.
