When one uses DESBUF, it should be preceeded by CONWAIT as DESBUF also
clears CMS' console output buffer.

There is a lot of information around about this matter but unfortunately it

You have to define the printers to your second level VM system.
My guess is that you also had to define them on the first level system.
Look at the SYSTEM CONFIG on the first level to see if you have a RDEVICE
