But IMHO, that was long enough for them to figure out that an OOP sensor was needed, as all it took was running out once to realize it's a necessity for a desktop machine that prints a lot.

Also the OOPS sensing is much more important for the programmable 97, since it might be running unattended. Rather than continuing and failing to print, it will stop so that you can load more paper when you notice, then resume running.
