I’ve not been able to find a driver which enables duplex for this printer
The closest is Expression ET-2750 Business Edition (but that is for the older model - duplex option disabled)
None of the Epson ET-x850 drivers manage to print anything, just empty pages - very little in options
Is it just a matter of time waiting for the correct driver to be published, or is there another workaround
I’ve also tried the Generic drivers with even less success
I do use a ET-4550
and duplex works for me.
What drivers did you install already ?
