Printed white comes out beige

Recently I got a new printer ( Canon LBP5000 - color laser ) and I have a problem when printing from Photoshop ( CS ). When I print a picture, white comes out beige, and all the colors are off a bit. When I save that same picture and print it from another program everything comes out ok. I have attached pictures to illustrate the problem. The first one is the image file printed.

The second one is a photo of a sheet of paper with two printed images on it. The top one was printed from Photoshop, and the bottom one from some image viewer program.

Any ideas?

Hm...
In your print preferences what is selected?
PS manages color or Printer manages color?
Might want to play with that...

Dont know who manages color. Where do i find that option in CS1?

This might give you the help you need:

Thanks. Problem solved. Once i changed "Intent" from Absolute Colorimetric to Perceptual ( in: Color Management - Print Space ) finally white came out white.
