I tried after a long time I didn't touch it... I reinstall Morphos avoiding update, I've installed my printer Epson Stylus Photo 750 as usbparalell.device and I tried to print from shell. This time it works! :)

I have no idea why it didn't work before, maybe because of Mac Mini USB ports which don't work with all mouses, maybe because of Morphos update from 2 to 3, no idea.

Now in case for the future I want to print .pdf or whatever file from any other software, do I need also Ghostscript installation/configuration?
