My ASR-33 Teletype punches the feed hole along with the code holes. It
uses friction-feed rollers to pull the blank tape off the roll and feed
it into the punch (which has 9 pins in line, 8 for the data and a smaller
one for the sprocket hole).

All of the Teletype and computer tape that I've
seen was prepunched. I've
never seen a Teletype or computer type machine that could punch the
sprocket holes. I think I've seen unpunched tape but I don't remember what
it was for.
