Comment 3 for bug 390016

Another data point: I have this issue, but with an Epson printer (ET-4550). Same behavior. I've tried with `-o Duplex=DuplexTumble`, `-o sides=two-sided-long-edge`, and both at the same time. For kicks, I also tried `-o sides=two-sided-short-edge`, and no option; any duplex print comes out tumbled.

This may mean hplip is not a cuplrit, except that the Manjaro printer package has a hard dependency on the hplip package so it was installed. Still, it's unlikely the issue is with the driver -- or that it's the same bug in *all* drivers.

`lpoptions` returns multiple duplex options; the defaults are for no-tumble, but the output is tumbled anyway.

```
$ lpoptions -p myprinter
