not really my field of expertise, but -
probably one should measure the spectral reflectance of each printed 
primary color to come with a good color calibration ? Or is that purely 
academic ?
I had found it rather difficult to get a feel what the a laser printer 
does internally, what happens between the RGB values in the PS or PDF 
file and the beam intensity. Has the user enough control over that 
process to justify a calibration ? Anyone got (negative ?) experiences 
to reproduce colors and shades between self-calibrations of a printer ?
