Comment 42 for bug 885118

I am now able to duplex print on the Epson SX535WD. Followed steps:

- go to http://localhost:631/
- select 'printers'
- select your printer (should list your printer). Printer will be shown with two buttons: 'maintenance' and 'administration'
- under the 'administration' button you have to select 'modify printer'
- click continue, twice
- select the epson inkjet printer 1.0.1-1lsb3.2 driver (instead of, in my case, epson inkjet printer escpr 1.2.2)
- click modify printer.

you should now be able to select duplex mode.
