TurboPrint & PrintFab

Sorry it took a while, but it's my parents' printer and I don't often have access. I just tried the Epson Stylus SX 525 WD driver and the duplex works. The devel on TP can go ahead and copy/past the code for the 42WD ! I don't know if there are drawbacks to using that driver on the 42WD, but I left ...

Sure, but where do I download it ? A quick search turned nothing.

Hello all,
I'm using TurboPrint on an Epson Stylus Office B42WD, and the only duplex options available are Off, Manual portrait and Manual Landscape. Am I missing something ?
I was using 2.26-1 and just upgraded to 2.26-2, no change.
Ubuntu 12.04

Thanks.
