Option in 365 to MANUALLY print on both sides!
In my old Microsoft Excel, I had the option to manually print on both sides. In the 365 version, I have no option to do that. So even if my printer says it will duplex print, it still prints 2 sheets because my printer needs a MANUAL fix of paper (which I don't mind doing). But not having that option is really fu*king up my work and wasting a sh*t ton of paper. Now I have to take more time to print each document section by section because of that non manual feature.
