Windows 10: Change available paper in windows

Help me change "available paper" to A4 I've been printing in wrong size for 3 years and I still haven't figured out how to change it. It shows A4 on all other windows devices I have ! What could be the issue ? Is it maybe because my region is set to USA where they use Letter ? I tried changing it to countries which use A4 but it didn't help.

How to change Microsoft PDF printer default paper size from Letter to A4?

Hi, my problem is Microsoft Print to PDF is printing a Letter-sized doc as A4. In the Microsoft Print to PDF Properties dialogue box under 'Features', the only paper size listed under 'Paper available' is A4. But if I click on 'Preferences' and then 'Advanced'
there's a list of paper sizes available that shows 'Letter' has been selected. So it seems the problem is the Paper/Output option I've selected as 'Letter' is not changing the A4 'Paper available' feature in the Microsoft Print to PDF Properties. Does anyone
know how I can change that or add a 'Letter' option to the Properties dialogue box? It's really important I get this fixed. Thanks in advance if anyone does know.

 

Paper sizes

I'm running Windows 10; I have an HP Officejet 7610. I've been using an old version of Adobe Photoshop Essentials (on an old Dell laptop---incredibly slow). I just subscribed to Adobe Photoshop (as the software doesn't seem to be available on CD anymore)
With my old program, I could print poster sizes 11 x 17 and 13 x 20. These options are no longer available when I using Photoshop. Any suggestions for adding paper sizes to the dropdown list?
