Teodoro,

If you are using a current Linux distribution (anything in the last couple years) then you should be able to just use the IPP Everywhere driver with this printer since it supports AirPrint and Mopria (both IPP), and that driver will give your duplex support.

That said, I'm not sure what we would need to do to add duplex printing support for the printers that support it - the HP PCL3GUI commands are fairly well-known, but we'd need to research the ESC/P command(s) that Epson has added for duplex support.  Plus whatever plumbing would be needed to keep track of the current page (to know when to eject the page vs. when to pull the page back for printing the other side...)

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.
