Specifying frame to print

I have a scene with 2 printable frame which I have assigned the #p lable to. However, it always prints out both frames, no matter which frame is current. I noticed in the print dialog that comes up, under which pages to print, "all" is the default. How do you limit printing to the current frame only.

Thanks

to designate a print area you must lable the frame #b and use bmovie...

At least its what it says in the help document. Im using it and it work find for me but my movie contains only this particular frame to print.
