Flash Player 9 - printing blank (printjob)

Hi, first post.
i am having a problem with the printjob class. i developed an application which dynamically created pages and sent to print fed from xml. all worked fine in flash player 8.

now with the update to flash player 9 the pages print blank.

the right amount of pages are spooled just nothing is printed (ie 4 blank sheets)

the printing still works fine in flash development, or in standalone flash player…its only the browser plugin (ie, firefox, opera - all PC) that all fail to print anything at all.

anyone know any reasons why this could be happening?
