Routine to print ROM demo from hp photosmart 3210?

Hi,

Anybody know the button-pressing routine to print the internal ROM
demo on the hp photosmart 3210?

For instance, on the hp officejet 5510, press both the right and left
arrows simultaneously and hold for 5 secs and that will print a demo
page touting the model's features along with a nice color image....and
of course the hp logo.

Thanks
