Thanks for the information.  It turns out I'm not being able to print
two-sided-long-edge with CUPS and my Brother HL-L2360DW.  I resorted to
using /etc/printcap and lpd's lpr (not CUPS's lpr) because I can then
set my printer to always do two-sided-long-edge, which is nearly 100% of
the way I print.

That's what I did as well.  I use a filter called ps2pcl.

lp|remote|brother|Brother HL-L2360DW:\
  :lp=9100@BRWB052162167A6:\
  :if=/usr/local/libexec/ps2pcl:\
  :sh:sd=/var/spool/output/lpd:\
  :lf=/var/log/lpd-errs:

But today I learned that the Brother HL-L2360DW supports PostScript and
I was able to set it up that way with CUPS.  I just don't use because I
never want two-sided-short-edge or one-sided, which is all I can get
with CUPS for whatever reason.

Turns out qpdfview is a pretty usable PDF viewer and it's the one I'm
using the most here.  I think qpdfview is the closest thing to
SumatraPDF (on Windows), my favorite.

Thanks!  That works.

Good to know.  Sometimes we produce PDF for screen viewing.

You seem to know a lot about PostScript.  So here's a question.  When I
want to print two-sided-long-edge, is that a command included in the
PostScript document itself (and then sent to the printer)?
