too much magenta in printed page

[krackedpress]

Using Ubuntu 9.10 and latest HPLIP, the Linux drivers for HP's Color Laserjet 2600n is placing too much magenta on the printed page. Grays have Magenta in it. Looking at the "test print" page that is printed. The Grayscale and Black is mostly Magenta % rather than Black %.

When printing in black/white only this problem is not there. But when you print in color, everything has a magenta tint.

This does not happen when running the Standard Window drivers on Vista.

I have tried Foomatic, hpijs, and hpcups driver options for the printer, but each one gives an over magenta printout.
