I have an old line printer that has a spinning wheel that has the characters around the perifphery (SP?).
A soleniod whacks the paper from behind, pushing it into the whell, which is inked by another spongy roller that rides on the wheel.
The wheel goes across the platen on a thread screw rod.
Wieghs MUCH more than a boat anchor and I paid $200 for it back in late 70's.
Daisy wheel!
