Re: [Gimp-print-devel] [pam.roberts@virginnet.co.uk: [linux-usb] Epson Stylus Color 760]

OK, I checked in the fix.  I also checked in something else that might
help -- I had the inter-jet separation set to 6 lines, which is
unusual; usually it's 8 with these printers.  It's possible that it
really is 6, in which case a separation of 8 will cause somewhat
strange effects.  However, my weaving code may not be correct for a
separation of 6; it needs more testing, and if that was the case,
things simply wouldn't work.

If you still have problems, try this.  Find the line in print-escp2.c
(in the latest version 1.63, it's lines 495-499) that looks like this:

  /* Stylus Color 740 */
  (MODEL_PAPER_LARGE | MODEL_IMAGEABLE_600 | MODEL_INIT_440
   | MODEL_HASBLACK_YES | MODEL_6COLOR_NO | MODEL_720DPI_DEFAULT
   | MODEL_VARIABLE_4
   | MODEL_1440DPI_YES | MODEL_MAKE_NOZZLES(48) | MODEL_MAKE_SEPARATION(8)),

Change the 48 to 32.  This will reduce the number of nozzles it uses,
but if my information (about 48 nozzles) is incorrect, this has a
chance of working.

Also, if this works (due to the weird init sequence, presumably),
could you try printing as a 640?  If that fails to print, then we know
the 640 needs the init sequence also.
