I am trying to use Photoshop Elements for Android to print a photo at 2" × 2". There is no way to resize the print size in the app only to change the pixel resolution. I have been advised by Adobe support to use the pixel to inch converter found at https://pixelsconverter.com/inches-to-pixels however I find the conversion to be unreliable. Additionally I find that I would first need to know the printers default DPI. Adobe support has been unable to advise me how to proceed and suggested I leave the question here on the community. Any help or advice is appreciated.
Sincere Regards and Happy Holidays

2x2" equates to an aspect ratio of 1:1. Unless the source picture conforms to this ratio, you will not be able to resize it without distortion.
If there is unimportant information on the photo, you may be able to crop it to 2x2", discarding the excess and retaining the object(s) of interest.
Another option is to create a blank, new file at 2x2" and use one of the selction tools to select the object(s) on the source file, then copy/paste to the new canvas. Note that the pasted object(s) will come in on a separate layer, and you can position same wth the move tool, and resize to some extent with the corner handles of the bounding box.
