Typically, when you print you will get on the paper exactly what you see on the screen. A couple thought though, what color is the edges of the indicators? Black should show up as black, but if you are using a very light color it might get interpolated to white in the printer.
Could also be something funky with the printer driver (I have a Brother laser printer that always wants to print LV output upside down and backwards--I have to hold my printouts up to a mirror to read them...).
Could you post the front panel you're printing so some of us can try it? That would help determine whether it's a problem with your computer and printer, or there's something funny in the image itself.
