Hello friends, first of all THANKS for your kind attention to my problem!
Sorry for wasting your time, but now it's evident to me that I must hope for the "Manual Duplex" supported in HPLIP (or in Ubuntu). Many cheap printers does not provide the automatic function double sided; so I suppose that the program improvement in that direction will be very liked to a lot of people.
Thanks again and best regards, Enzo.
