Diego.

Diego, the guidance the author provided is of limited to no use (based on my experiments with 2 82143A printers) and from a post above.

The quote in post #1 is from the second edition of the book.

Perhaps the earliest printers had had power over I/O, and if true, then I expect they'd be both coveted and well known.
