Documentation
Output stream print uses by default for outputting a character.
This may be any function of one argument. It may also be a buffer (output is inserted before point) or a marker (output is inserted and the marker is advanced) or the symbol t (output appears in the echo area).
Probably introduced at or before Emacs version 1.1.
