Planner-list Print in color

Hi

First excuse my poor english, I hope you can understand what I mean :-)

When I will print something from the planner, I always become only
outputs in black and white (or grey), only one line from top to
bottom of the page is in blue color.

Do you think, this is a problem with my printer-driver or is it not
possible to print in color?

My printer is a HP Photosmart 2575 all-in-one. I work with xubunt 9.04.

Thx for help.

Regards,

Hans
