Digital BW, The Print

The samples I tested were printed with an HP 7660 with the gray ink on the
"swellable" HP, Kodak, and Ilford papers that were available in March 2004.
All those papers did about the same in the tests, by the way.  The HP inks
definitely do make a nice very glossy print.

The HP I'm using is the 7660.

I install ONLY the #59 cartridge (3 grey inks). The other "chamber" 
is only. 

In the HP drive, under color, I activte "Print in Greyscale".

The prints look really nice.
