I don't see this behavior with the current development sources.  At
least the printed version of the figure looks correct to me.  But
after the print command the colorbar is hidden below the main figure
on the screen.  I see

  octave:27> imagesc(1./hilb(33)); colorbar
  octave:28> kids = get (gcf, 'children')
  kids =

     -7.0957
    -13.0349

  octave:29> gca
  ans = -13.035
  octave:30> get (kids(1), 'position')
  ans =

     0.827500   0.110000   0.046500   0.815000

  octave:31> print a.ps -dps
  octave:32> kids = get (gcf, 'children')
  kids =

     -7.0957
    -13.0349

  octave:33> get (kids(1), 'position')
  ans =

     0.688000   0.110000   0.037200   0.815000


I don't know why the position of the colorbar is changing with the
print command and I'm not very familiar with the colorbar code, so it
would be helpful if someone could help debug the problem.
