Hi Andy

I must have missed your message when you sent it, I have just found
it lurking in the far corners of my inbox.

As Robert says, the dithering support is all present, it just
needs the "nuts and bolts" bits sorting out.

What are the two extra colours - I assume they are "light magenta"
and "light cyan".

How do you tell the printer to expect the extra colour planes? This
could be what the "configure palette" command is for, or it may be
coded in the "configure raster data" command. Neither of these is
documented by HP as far as I can tell.

What order are the planes to be sent to the printer? For normal
colour, they are sent in the order "KCMY", is it now "KCcMmY", or
maybe "KCMYcm"?

Does the photo mode support more than 2 level dithers (like the
800 series)?

Other than that, it should be quite easy!

Dave Hill
