HP Color LaserJet 2840 Slow ppm

My CLJ 2840 is extremely slow to print in black and white. I chose to print a PDF in grayscale and it is only printing at 5 ppm in black and white. It is going to take forever to print this 2000 page document. Please help.

It is almost like it thinks it should be in color printing mode.
