Double-sided printing with CUPS + Gutenprint v5.3.3

Hi,I own an epson ecotank 2750 and I'm using the CUPS + Gutenprint driver
v5.3.3 on debian stable (and testing). I think your driver is the best, and
also the most complete among those available for linux. At the level of
settings it is also much more equipped than the official one in windows.
However, it lacks a simple but fundamental function.. double-sided
printing. I'm trying them all, but every app tells me that it is either
"not available" or not selectable. And this only happens with the driver in
question, with the others the option is available,because the printer is
enabled to do so. Is there anything I can do to print with your driver also
double-sided? Unfortunately when I print a lot of pages it is essential.
I am attaching a screen of evince pdf reader while I try to print.
