This fixed it for the pdfs for me: lifewire.com/reset-mac-printing-system-to-fix-os-x-printer-problems-2259970 Still need to connect my printer though :)

Same issues after upgrade to BigSure. Can't save as .pdf in Word, nor print to pdf across Mac iOS, nor use my brother Hl5240 browser. A reinstall of Office did'nt do it either.
