A plug board had to be setup defining the print position, for each column read of the card, to be used. Now, while there is no card reading printer (at least none I know of), there are (alphabetic) interpreters (like the IBM 557), whose purpose was to read a card and print one or two lines (depending on model) onto the very same card.Īlso, beside the fact that they could only print 60 characters per line, they as well need to be programmed to do so. Then again, it depends on your values of 'program', 'directly', 'loading' and 'printing'. The simple reason is that there was no need to do so that would justify construction of a special purpose machine. Neither during the time pf punch card processing (pre-electronic computer) nor and even less after electronic computers became a thing. Was there any equipment which could directly print out the program or data on a stack of punchcards, without first loading the deck into a computer?
