It was way back when (look up a GE 210) and it dates to even before that. But in answer to your question, printers are still too slow to ask users to wait for the printer to complete before typing more in say Word.
I was confused by the SPOOLing recent days. I found that the origin of SPOOLing was attached to the IBM 1401. According to the introduction, i think the SPOOLing's appearance because of no hard disk or other devices which can connect to mainframe at that moments. am i right or not?
well, we have so many device which can support fast input/output function now, why could SPOOLing remain and even more prosperous?
