I just reported a similar bug for 12.04 LTS, tagged 1081065
I confirm the above for my Epson printer.
Any file does not print in duplex (tested both pdf and office). The duplex option just is not selectable (either greyed-out or auto-resets to single page). 10.04 LTS gave no problems.
Since it is more printer brands and was not a problem on 10.04 I suspect it is not the printer brands drivers but Ubuntu that causes the flaw.
Printer: Epson SX535WD
Drivers I had installed on 10.04 LTS:
- epson-inkjet-printer-escpr_1.2.0-1lsb3.2_amd64.deb
- epson-inkjet-printer-201106w_1.0.1-1lsb3.2_amd64.deb
Drivers I have installed on 12.04 LTS (1 updated, 1 the same)
- epson-inkjet-printer-escpr_1.2.2-1lsb3.2_amd64.deb (newer)
- epson-inkjet-printer-201106w_1.0.1-1lsb3.2_amd64.deb (same)
