SPECIFYING INPUT PARAMETERS
XEROX DOCUPRINT 180 LPS PDL REFERENCE 4-43
If a selected HOST type is inconsistent with a selected LABEL type,
the PDL issues an error message and automatically substitutes a
valid label. Do not code the LABEL parameter of the VOLUME
command in cases where it is not appropriate for a particular HOST
type. Refer to the “Offline specifications“ appendix for more
information on offline formats.
If an online job (JDE) is called out in an offline JDL that changed the
system default values, the job may print incorrectly. If this happens,
separate and run online and offline jobs independent from each other
