   That sounds kind of drastic, but I suppose if high speed microweave
   is supported by a given printer, it might obviate the need for
   softweave with that printer.  I wonder the same issues would also
   apply to similar genre printers like the stylus color 800 and 850?

If we can make softweave work, I'll happily put it back in, but if
not, we can't use it.

   Again, I'm not an expert at printer internals, but in case it might
   help, here's something I observed when testing the driver: When
   using the microweave mode, the printer advances the paper a small
   amount after every pass of the print head, whereas when using
   softweave, several passes (either three or four, I can't remember
   right now) are done before the paper is advanced; and when it is
   advanced, it is advanced the same small amount as it is during
   microweave.  This probably accounts for the perceived speed
   difference - making microweave seem 3-4 times faster than
   softweave.

Could you time it with a stopwatch and verify that the times really
are about equal (or that microweave does better)?

   Once again, let me know when you have taken a cut at it and I'll
   test it out.  For two years I've been looking forward to the moment
   I could print out a photo at 1440x720 from Linux and have it be as
   good as the same printed from Windows..

I'm working on it right now.
