   PROGRESS!!!!
   With freshly grabbed & compiled stuff from CVS ~1:00 PM Sunday EST:

   900 driver:
   360 dpi WORKS
   720 Microweave WORKS

Those are "back compatibility" mode.  What's the quality like?

   720 Softweave - blank pages
   720 High Quality - blank pages
   1440x720 Softweave - nothing comes out? have to 2xcheck

That's unfortunate.  We need to understand the difference between the
900 and the 740 in this regard, because at this point I have reason to
believe that the 740 prints correctly in softweave modes (of which all
three above are).

1) Could you try to print a small image in the top left corner of the
   page (left=0, top=0), using 720 softweave?

2) At line 1053 of print-escp2.c, you will find the following:

      fwrite("\033(D\004\000\100\070\170\050", 9, 1, prn);

   Try removing this line.

3) At line 1016, you will find this:

      if (escp2_has_cap(model, MODEL_6COLOR_MASK, MODEL_6COLOR_YES))

   Try changing it to

      if (1)

4) You will find this at line 628:

  /* 13: Stylus Color 900 */
  /* Dale Pontius thinks the spacing is 3 jets??? */
  /* No, Eric Sharkey verified that it's 2! */
  (MODEL_PAPER_LARGE | MODEL_IMAGEABLE_NEW | MODEL_INIT_440
   | MODEL_HASBLACK_YES | MODEL_6COLOR_NO | MODEL_720DPI_DEFAULT
   | MODEL_VARIABLE_4 | MODEL_MAKE_XRES(360)
   | MODEL_1440DPI_YES | MODEL_MAKE_NOZZLES(96) | MODEL_MAKE_SEPARATION(2)),

   Try changing the MODEL_MAKE_NOZZLES(96) to MODEL_MAKE_NOZZLES(32).
