depends

are they trying to export a PDF from Microsoft Word? because Microsoft makes that difficult nowadays

Can’t you just print and choose “print to pdf” as your “printer”?
Yup, super difficult. Its not the default, so no one can find it.

it’s buggier than it used to be, though

Apparently then it is bad for formatting and reading apps for the visual impaired can not pick up sections when they have been pre assigned (but I didn’t test just saw a real, need confirmation)
