Acrobat does not print normally, or at all

This started a few months ago. I don't print much, but lately when I open a PDF in Acrobat (Win10), it will either print the item very small (USPS shipping labels the size of business cards), or take a full page document and print it turned sideways on half the page, or upon opening the Print Dialogue Box, it wants to Save-As a .PRN file, will not print. The only way I can print these documents correctly is to use Chrome. I have the latest versions of Win10, HP6950 firmware and driver (from 2016), and Acrobat 20.009.20067. As I said, this only started a few months ago. Any idea how to fix? Thank you.
