Problem Description: 

In a Classic with newsprint software/Zebra card/printer attached 
 and print job fired ,the system hung. There was no  activity on the keyboard
(ie. no numlock or caps lock light response). L1-A key sequences were
inoperative and the system would not respond tp to remote ping commands
and system had to be power cycled.
