I’m old. When our teacher brought copies to class we would all smell them. What was that called?
Spirit duplicator or colloquially “ditto”.
Ditto! Ditto sheets! Thank you!
Im slightly less old (albeit still old) and this is my ditto ditto

There was also mimeo, or some similar spelling, from mimeograph

Looking over that, I’m not certain those would smell the same way otheroptions did, but at my elementary school, that’s what teachers usually called them. If it wasn’t that, it was dittos
Mimeos worked differently and didn’t smell nearly as strong, but they needed special paper (“twilltone” in the fanzine world) and the stencils and machines were more expensive than their ditto counterparts. You’d use them for large copy runs since a stencil could run off unlimited copies. Ditto masters were basically carbon paper and were good for maybe 30-50 copies depending. About right for a batch of class handouts. Dittos were also relatively clean and convenient to operate. Using a mimeo generally made a mess.
