Print cannot scale up
Printing a pdf feature cannot scale up. Independently from the choice of file or printer, printing at a scale more than 100% does not change anything. Unfortunately this extends to the "Fit to page width" option - attempting to print a document with pages smaller than paper size produces an unscaled, small document on a part of the page.

It shows Microsoft print to PDF this would indicate you don't have a printer software/driver installed from what it's showing. Did you click the down arrow on Print Destination to see what other options there are? Sometimes Print to PDF only allows certain changes unless you select what printer in the options to be able to change scaling options. And PDF are usually set so one can't change them as well.
As I said, the issue is independent of the printer choice. I chose to show that even "print to pdf", which has no hardware constrains, has the issue -- but any other printer I tried this with was the same.
