Yes, because your monitor uses RGB and your printer uses CMYK. The conversi= on between thetwo is not too complicated, but actually getting the same out= put from the two is hard. RGB is an additive model, CMYK is subtractive (re= ad about the different models, wikipedia will do). The color impression you= get by looking at the output is generated in completely different ways.

Most office printers cope well with RGB (sRGB) colors, a lot of inkjet prin= ters even better than with CMYK colors, because they're optimized for h= ome dummy use.

But (as Christoph pointed out) your printer can be as great as it goes, you= 'll never get a similar color impression if your monitor's set to s= ome extreme setting - and most monitors that I saw outside of the graphical= branch are set to "nonsense" settings, e.g. max contrast.
