These aren't really options; they're descriptions of the printer (firmware + hardware).  The
firmware expects a certain number of rows, starting from a specified row (usually, but not always,
the first).  We could in principle send dummy data for the first N rows, but I don't recall that we
have a way to do that.  Skipping rows would be much harder.  NozzleSeparation really is the
specification of the distance between nozzles; it's very unlikely that that would ever work on any
printer.
