I worked on a predecessor to that at Xerox at the start of the 1990s. The first was the Xerox 4850 which was the size of 3-4 clothes washers, cost several hundred thousand dollars, and printed at 50 pages per minute in black plus one color (Xerox called it Highlight Color), but no CMY. It was exactly for the logo use case you mention. A big customer was AT&T for printing phone bills with their blue logo on it. It let them replace many millions of pages of letterhead not sold by Xerox with blank paper sold by Xerox. Xerox loved paper phone bills.
