When a TCP/IP-attached printer is to be used with JES, it must be defined for deferred printing mode with JES.
FSS(FSS1),PROC=PSFPROC,HASPFSSM=HASPFSSM PRT1 FSS=FSS1,MODE=FSS,PRMODE=(LINE,PAGE,SOSI1), CLASS=C,UCS=0,SEP,NOSEPDS,CKPTPAGE=100, DRAIN,MARK,TRKCELL=YES
The above example is correct for JES2 3.11 and above. For earlier versions of JES2, the statement is named FSSDEF and would be stated as FSSDEF FSSNAME=FSS1.
The value you specify for the PROC parameter must match the name on the PSF Startup procedure.
