I have dealt with terminals with passthrough printers before, but it was three decades ago, and I've certainly never heard of a printer communicating *back* to the host over this channel
I've also set up passthrough printers on terminals - which were hanging off muxes ... it's a serial connection, so bidirectional commumination should be fine, and more recent printers would make use of that.
And in fact, when we ran out of mux ports, we even hung an extra terminal off the passthrough port, so bidirectional worked :-)
These were physical serial terminals, of course - I don't remember having to get a terminal emulator to do this. It also wasn't on Linux - some were on SCO, and the others might have been on some kind of mainframe - a government department. We weren't involved in that side of it.
