We've just discovered a bizarre incompatibility between the LaserJet and
the LaserJet Plus.  It appears that when you download a patch of raster
graphics to the LJ+, it comes out ten dots to the right of where it should!
Characters surrounding it, including characters that rely on the raster
sequence leaving the cursor in the right horizontal place, come out in
the proper locations, so it's not a cursor-positioning bug.  A quick fix
is to insert a leftward ten-dot motion just before the "raster begin"
sequence and a rightward ten-dot motion just after "raster end".  This
cleans things up in all the test cases we've tried so far.

The local HP people have been told; I will report further on this when
they get back to me.
