What is the exact printer make and model? The configuration may not be correct for the device description parm MFRTYPMDL.
Perhaps you want to try the following:
In your Printer Device Description change;
MFRTYPMDL into *WSCSTNONE
SYSDRVPGM into *IBMIPPDRV
At the bottom at Additional Parameters
WSCST into QWPDEFAULT
Library into QSYS
See what happens next.
let me add some comments.
