I think is possible, but not straightforward. The base colours are in a 
css file. This could easily be overridden in a custom css file 
specifically for printing.

But the line/bar/pie segment colors are chosen by the java script code. 
The jqplot code is flexible enough that you can even override these by 
setting options for the jqplot object, but it could be more difficult to 
only do that for printing.

Overriding line styles is similar to overriding the data colors: you can 
do it by setting javascript options. Again, it may be more complicated 
to do this only for printing.
