Most 3270 & 5250 class terminals used printers that were similarly attached
(co-ax or twin-ax). Later models might have supported serial printers, but I
doubt it. There were several vendors who made "protocol converters"
specifically so that users could attach cheap parallel printers to their
mainframes and midrange systems. Andrew was one that I recall.

IBM also made some weird terminals that almost defy classification,
especially for word processing applications.
