Double sided printing grey-out when printing pdfs from internet.
I can not double side print pdfs. It doesn't matter if I'm printing direct from the web or if it's been downloaded and I'm printing within adobe. double side option is always greyed out and can not be selected.
I've tried everything including changing the printer default options through terminal, caps modifications per adobe instructions for Adobe acrobat reader DC, ... can anyone help? Using basic canon home printer. There are no options for printer preferences, so there's no way to enable directly with the printer itself. Did not have this issue with previous PC desktop and same printer. FRUSTRATED and in need of ideas.
