[Xprint] HP Deskjet 870 model config files and color problems

[orangevixen at wolfsinger.com]

Hi, I was not able to search the lists if this question was already 
answered (list search page goes to list archive download page) and I did 
not find it in the FAQ.

When I use XPutImage() with a 24 bit depth TrueColor X Visual to put a 
colored image on to X Print's drawable, the colors that are not pure in 
color (such as yellowish grey) come out as gray or some other color.

I am not an expert on printing but I was wondering if I need to do the 
"dithering" on my client side or does X Print do this past its DDX level?

I have an HP Deskjet 870 CXI and I was wondering if there is a model 
config file I should use (instead of the all purpose PS model). I wasn't 
able to find a place to download model config files on the FAQ or the web 
page.
