I think it's a trope because most people really don't need color printing, so that advice is appropriate for them.

I, for example, have only ever used my printer to print such things as tickets and documents which must be mailed for bureaucratic reasons. My hunch is that this describes many others too.

I think that “most people” really means “most programmer type computer nerds on hacker news.”

I think most people prefer having color. The top 8 printers on Best Buy’s website are all color and/or photo printers.
