[Gimp-print-devel] New Epson 1520 Print Files

[David R. <d_...@nc...>]

I have downloaded the newest Epson 1520 Windows driver
and have generated the following new print files:


http://www.nccn.net/~w_rosky/dsr/e720new.prn.gz

This is a new version of the 720dpi "microweave" print
file.


http://www.nccn.net/~w_rosky/dsr/e1440new.prn.gz

This is a new version of the 1440dpi microweave print
file.


http://www.nccn.net/~w_rosky/dsr/e1440newFO.prn.gz

The new driver has an additional microweave mode called
"Super" which is only available at 1440dpi on certain
printers and generates something called "full overlap 
microweave".  According to the help file, this mode helps 
reduce banding even more than standard microweave.  Indeed, 
one of my blue nozzles is currently partially clogged and 
this mode did actually show less banding than the normal 
microweave mode; however, it showed ever-so-slightly more 
grain.

Let me know if there are any additional testing or print 
files that would be helpful.

I don't know why it would show more grain (unless it's due to your
partially clogged nozzle), but it certainly should reduce banding.  It
uses a spacing of 15 rows consistently.  It's basically equivalent to
our "1440 dpi highest quality" mode.

   Let me know if there are any additional testing or print 
   files that would be helpful.

That should be enough to get me started.  Could you try the following
patch?  It's possible that it won't compile; my sandbox is currently
broken because of some code I'm working on; in that case, my
apologies.  If it works, could somebody check it in?

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:

That's what I'm trying to do.

Either do "make print", or add an extra argument of 1 at the end of
the call to initialize_weave() in escp2-weavetest.c.

I added the extra argument of 1 to the end of
the call to initialize_weave in escp2-weavetest.c.
It got a little further but still failed:
