Thanks, Eric.
But the problem seems to be only with the browsers...at least browsers that are not Safari. (Firefox, Chrome, Brave...all give me the same problem. Not Safari.) I have no idea what settings may have been changed that would affect all browsers (again, except Safari.) I have no problem printing from any other app...I know about paper size/orientation/scaling/etc. (BTW, I do know how to work around the problem, besides simply just using Safari :) I can choose to save the pages as a PDF, then print the PDF with no problem. But it still mystifies me as to why these other browsers are using a different print dialogue/system.
I even get a different print dialogue box with those...here are some screenshots to demonstrate:
The top image is the print dialogue that comes up with those other browsers. It is not the usual print dialogue box that comes up with everything else, including Safari. Although the settings look right, and even the preview image looks right, the fonts and images on the actual printed page is about 4 times too big, and I only get a corner of the content on the printed page, but it fills the entire paper. And the other content is not printed at all.
The normal, or usual, Print box is the second image below. So somewhere those browsers are getting instructions to use some other printing system.
Any ideas on what's going on here? (I suppose it's not an Apple issue, so I'd understand if you are not allowed to advise.)
