I have my printer configured (CUPS) to use double-sided printing.
Most of the time this is what I want.
Occasionally I want to print single-sided. In the evince print dialog
I can click on the Page Setup tab. In the Layout section I set the
"Two-sided" widget to "One Sided" instead of my default "Long edge".
Then click on the Print button.
The document prints, but it still comes out double-sided. Even though
the print dialog box is now set to "One Sided", this setting is
getting ignored.
Thanks,
Drew
