   What commands? To shown the ink levels in the cartridge? to help to
   change it?  ...

No, what UNIX command to use to send the file to the printer..

   :-)))) 
   Others software use standard drivers for printing with theses inks.
   They only recommand to use UCR than CGR separation table but it is not
   necessary. And to change the saturation.

Well, I don't understand how that works.  The printer doesn't know
what kind of ink cartridge is in the printer; if you try to send
something to the printer, presumably something will create the color
separations and send each color to the printer.  Without something or
other to tell it, how will the driver know that "yellow" is really
some percent gray?  Surely you have to tell it somehow that you're
trying to print a black and white picture using special inks, rather
than a color picture using color inks (or a black and white picture
using color inks), no?

   May be a "how-to" file which explain as the driver works should be
   interesting (at least for me).

There's some stuff; check out README.dither (which is a bit out of date).
