I called them printing terminals. They had a keyboard, a printer and usually
a serial interface.
Besides IBM, Xerox had the 1610 Printing terminals based on the 630 printer
mechanism. There was one based on the NEC spinwriter printer. GTE had the
Termnet series of printing terminals (300 & 2120s) and of course the
venerableTI Omni 7XX series of thermal printing terminals.
If you find one of these I may have manuals.
