Even for the mid 1970s MVS 3.8 OS IBM placed in the public domain nobody
uses anything but 3278s except maybe for console logging (not as a general
console). The printing terminals were useful for OS/360 console loggers
but few Hercules users run OS/360. Bottom line and for everything else when
you're using a terminal with MVS it's a 3278 and needs a tn3270 client if
you are not direct attached. tn3270 covers 100% of normal use cases for MVS
terminals except if you insist on using an optional printing console. You
certainly don't need one.

Are you saying Putty's telnet doesn't support the printing terminals
Hercules supports? Because if that is not what you are saying then we seem
to be going around in circles. Telnet clearly won't work for a normal IBM
terminal.
