    Yesterday, one of the printers here in ITS began printing a Jetdirect 
    Diagnostic Page showing a S/W Exception 00fb and a core dump 
    ("Registers", "Stack", and "Register Pointer Memory Dump" in Hex). I 
    changed the slot, and the error followed (from EIO1 to EIO2), 
    therefore I guessed that the card was bad. Today another printer 
    began to share the same symptoms. I have a hard time believing that 
    two cards would go bad at the same time
    
    Has anyone else noted this phenomenon??
    
    Could it be a different type of printer attack than the port 515 attacks??

    (PS, I've already called John and notified him--he asked me to post 
    here (I'm also posting to the Security Focus list) for feedback.)
