[Gimp-print-devel] Epson Stylus 660

[Hrafnkell E. <he...@kv...>]

Hi

I have just bought a Epson Stylus Color 660. I just installed
v3.1.1 of the gimp-print plugin. I see that the Stylus 660
is not listed in the setup for supported printers.

I've been able to get output from the plugin in 360dpi mode 
when choosing Stylus 460, printing to a file and then catting
the file to /dev/lp0 (I'm currently using CUPS as a printing system
and it only accepts fileformats it understands, not raw data to
send to the printer).
When choosing higher resulutions the printer just feeds lots of
paper through it.

Can I help in getting the printer supported? I can both read
and write C code (I'm trying to understand print-escp2.c as
I am pretty sure my printer uses that printing language).
I've seen the documents on http://www.ercipd.com/isv/edr_docs.htm
but they don't mention the Stylus 660.
Are those documents the documents you use when writing the gimp-print
plugin?

Btw. I know that you guys are trying to improve the dithering code.
I just did a quick search for articles on error diffusion and inkjet
printing in the online article database at my university. I found
an article called "Error diffusion with ink reduction for high
quality and high resolution ink jet printing" by Joseph Shu at
Epson Palo Alto Labs. Have you seen it? It appeared in the proceedings of
IEEE International Conference on Image Processing 1995.

Thanks
  Hrafnkell

PS: Is the patent situation with dithering algorithms complicated?
