The latter was my point: it's exactly xterm (or whatever X terminal
application you are using) which (possibly) converts X events to
escape sequences.

In the case of xterm this can be configured via X resources.

Yes, that corresponds to my findings. I guess the "Print" key was not
a thing whenever the X resources for xterm were set up and nobody has
bothered to change them in the mean time.
