   Uhm, unless I'm doing something wrong here then I beg to differ -
   just got a fresh copy of the mainline and I still get the same
   results. Same thing for the print-3.0-branch, but maybe your
   correction hasn't been checked in yet.

So you're not getting any printout in softweave mode (720 highest
quality)?

In print-escp2.c, look for this:

  /* 4: Stylus Color 800 */
  (MODEL_PAPER_SMALL | MODEL_IMAGEABLE_600 | MODEL_INIT_600
   | MODEL_HASBLACK_YES | MODEL_6COLOR_NO | MODEL_720DPI_DEFAULT
   | MODEL_VARIABLE_NORMAL | MODEL_MAKE_XRES(720)
   | MODEL_1440DPI_YES | MODEL_MAKE_NOZZLES(64) | MODEL_MAKE_SEPARATION(8)),

It's around line 584 on the current mainline.  Try change

MODEL_MAKE_NOZZLES(64)

to

MODEL_MAKE_NOZZLES(48)

or if that doesn't work

MODEL_MAKE_NOZZLES(32)

If that helps, then my information about how many nozzles the 800 has
is incorrect (which is possible).

My Stylus Photo EX only has 32 pins, so I had to change the 64 to 32
to print, but when I did that it printed correctly.  Of course, I
don't have an 800, so I can't test it for real...

Nothing has been checked into the 3.0 branch yet.

   (With the current mainline, all my printers are gone from the print
   dialog - I don't have lpstat installed. The configuration doesn't
   pick up on lpc, for some reason. Not a complaint, just for your
   information.)

We do have problems in this area.  It's something we're thinking about
how to address.

   Done that, take a new look at the URL above.
