If checkpoint intervals are too frequent, printerperformance is significantly reduced. If intervals are too infrequent, and a PSF error occurs, the job has to bereprocessed from the last checkpoint. In this case, printer performance is significantly reduced if PSF errorscontinue to occur. The recommended starting value is 100.CLASS Specifies the output classes processed by the printer. By defining print classes you can handle disabledmechanisms.FSS Specifies the FSS for this device and must match the FSA name specified in the corresponding FSS statement.This parameter is required.MARKEnables form markings to be placed on the job trailer pages.
