z/OS Communications Server: IP Network Print Facility
SC27-3658-00
If this statement is not specified, the system uses the general
TCP/IP high-level qualifier, either specified via the DATASETPREFIX
statement, or defaulted to TCPIP.
Any high-level qualifier longer than 15
characters might cause truncations of the major and minor names used
as part of the data set name. This applies to the NPFPRINTPREFIX value
or, if one is not specified, it applies to the TCP/IP default high-level
qualifier.
