Yes, as some of you might remember, printer paper was very different then the paper we are familiar with today. Today, you can feed almost anything into a printer, but in the Analog Age, the paper was fed through all the really noisy dot matrix printers one line at a time using a wheel with little spokes on it. The paper was a complete long sheet with perforations for each page. The sides also needed to be removed.

It was kinda a pain in the butt, but you could make neat stuff out of the hole strips…
