Duplex is on (and the default at the printer), though I can't seem to force it off from the command line (I'm not the first: bug 47263). With the BR-Script3 PPD, it does the right thing from the command line with duplex on (i.e., Collate=False, 3 page document is 1-2-1-2-3-blank-3-blank, Collate=True is 1-2-3-blank-1-2-3-blank). Opening the same file with evince and printing from there, duplex on and collate off makes 1-1-2-2-3-3, duplex on and and collate on makes 1-2-3-1-2-3 (no blank back sides!). This happens with both the BR-Script3 and foomatic PPDs, both the old and the new cpdftocps. At least I can turn duplex off with evince. Attaching my 3-page test file for grins.
