I have to do a loop and the noprint option is useful. 
But in the end I want to see the results and even if I put the option print, nothing appears. 
Any solution? I tried to play with setting options manually but I did not manage.

I will investigate. Thanks for reporting it.

I have finally corrected the bug with a “print” option following a “noprint” one.
It is uploaded to SVN and will be availbale in tomorrow snapshot for version 3.
Sorry for the delay
