Worked with plenty of line printers that used this type of paper in the 90s, and they still jammed. And it was often very bad, as a lot of paper could get jammed together before the printer and/or operator noticed there was a problem - it's not just one sheet getting stuck. One of the jobs our operator had was to constantly clean, dry, and dust off the rollers that went in to those little holes on our high-speed line printer - the amount of paper dust produced by a few boxes of paper was astounding.
