When I execute a Manipulate exercise, the on-screen output shows the numerical value of a slider position without any problem [the result appears clearly in the little box below the slider bar]. But when I print the output cell, the numerical value is partially chopped off which is not good. I have found a solution by adding the code Appearance->"Labeled". For example, where one of my manipulatable variables is 'pelliclefraction' my code will read {pelliclefraction,1,.01,Appearance->"Labeled"}. Now the value of 'pelliclefraction' appears at the end of the slider bar and the printout of this is completely successful.
