Look ath the CHGDEVPRT-Command from your printer, press F9 to see all and go down to the driver settings SYSDRVPGM. Change it to IBMSNMPDRV.
But in another thread you told, that you can print SCS and have only problems with AFPDS, so the driver is not the problem.
Choose a HPPCL-WSCST in WSCST-Option.

Please make not 2 questions for the same problem.
