The difference in grain was very, very slight.  One thing that I
noticed is that in the "super microweave" mode, the head moves
at the faster speed used in 720dpi printing instead of the slower
speed used in the normal 1440 microweave mode.  Perhaps the
reduced settling time causes the very slight change.

That's interesting.  I wonder if maybe the best approach is
to fix the softweave mode rather than trying to get the printer's
microweave working.  The problem with the original softweave modes
seemed to be that the nozzle patterns and/or page advances were
not being interpreted by the printer the way the driver thought 
they would be.  If you could get those corrected you'd probably 
have it.

I tried the patch, but it didn't compile.  Here's the error message:

escp2-weavetest.c: In function `main':
escp2-weavetest.c:112: too few arguments to function `initialize_weave'
make: *** [escp2-weavetest.o] Error 1
