Printing with Koolmoves

I am having problems with getting Koolmoves to print using the print() function. I have a 1 frame test movie with a circle on the stage. I also have the following actionscript: print("_root","bmax");

When I run the movie, the circle is displayed in my browser, but it does not get sent to the printer.

If I put a button on the stage and use the print action, my swf is printed, but that uses the flash 4 player syntax and I need to use the print() function so that I can target which movie clip I print.
