For years (as long as Acrobat DC), across multiple machines, versions of windows 10 and versions of CC I keep gettting font errors when printing from various sources (specifically, browsers and MSWord)

This happens whenever I print to Adobe PDF (every time)

Windows 10 build 19041.508 (ver 2004)
Adobe CC 2020, Acrobat 2020.006.20042

This is the current error log generated:
%%[ ProductName: Distiller ]%%
Spectral-Regular not found, using Courier.
%%[ Error: invalidfont; OffendingCommand: xshow ]%%
