There is no print command distributed with Octave because with current
versions of gnuplot, there is no reliable way to save and restore the
current terminal type and output.

It appears the the next major release of gnuplot will support
something like

  set term push
  ...
  set term pop

so once that's available, we can implement a reasonable print
command.
