Explanation
This wait state code is issued by the 3203/3211
utility.  The printer is not online.  This will occur when the printer's
control unit has no power, when the control unit has been switched
off the I/O interface, or when the control unit is not a part of the
system.

Operator response
Ensure that the address of the printer specified
in the DFN statement is correct.  Ensure that the control unit is
online, and rerun the job.  If the error recurs, contact your hardware
support personnel.
