Printing to certain size in flash

I’m using the print function in flash to print out a certain movieclip. I only have one frame in my movie and the movieclip im printing on the stage is 290 x 365. This movieclip area prints out to a full 8.5 x 11 size on most printers, but on some it prints at actual size (290x365) Why is this?
Here’s the code:


Nothing is changed in the printers features that i know of, is this a common problem? Or better yet does anyone know how to print a mc to a certain size?
