   One quirk I've noticed, though, is that the head moves faster when
   using the 360 DPI raster.  It may be that there will be little
   difference in performance in bidirectional mode between these two
   settings.  If that turns out to be the case, then perhaps we can
   offer more conventional settings, and the drivers really could be
   identical except for the carriage width.

It turns out that there's a substantial difference in performance --
it took about 58 seconds to print a page in 720 DPI mode vs. 102
seconds in 720 DPI high quality.  So whatever difference there may be
in print head speed, it doesn't come close to making up for the extra
passes needed.

I think that based on this there is use for both 720 and 720x360 modes
(regular and high quality/enhanced) on the 1400.  On plain paper
there's actually very little difference between any of them.
