Text Box color problem

[bazwillrun]

Have text boxes filled with one colour gradient fill from the standar
palette, ,90% transparency at the top (very light color) to 100
transparency at the bottom.

all looks fine on screen yet when printed its ignoring the transparenc
and printing full colour at the top to 100% transparency at the bottom

any ideas as to why this might be
