Printing web site that won't allow it

I may have asked this before but don't recall the response and if so didn't
retain the response.

Anyway, what about those annoying web sites that don't show their content
when I use Firefox "Print Preview" and won't let me select and copy content
to move it to a word precessor to print there?

Anything I can otherwise try?

Web sites seem to be making it harder and harder to print their contents
for reference.

TIA
