Saving .eps from Simulink

I'm trying to save my Simulink models as .eps files. However, this seems to be not straightforward as the typical code of the forms:

print -deps -r300 -s myfig.eps 
saveas(get_param('P1q2', 'Handle'), 'output', 'eps')

results in the error below. I used both/either of those on my model with no differences in the error.

'eps' format is not supported with Simulink or Stateflow printing.

What am I doing wrong?
