Illustrator Print Issue

[theyallfalll]

When i try to print a bitmap in illustrator i ge this error:

Error: unregistered
OFFENDING COMMAND: imagemask

STACK:

-mark-
-savelevel-
-mark-
-savelevel-

Some times it prints the first time and then it gives me that error. I have an HP color laser printer.

thanks
