Route online application output to system spool. VTAM Virtual Printer lets you route output created by your online applications to the system spool.
VTAM Virtual Printer is a VTAM based application that emulates LU1/SCS or LU3 printers.. Each emulated or logical printer is defined to VTAM as an APPL statement. For CICS, a TCT definition is required with the NETNAME equal to one of VTAM Virtual Printer’s APPL statements. Your applications route the print datastream to the logical printer in the same way as real hardware devices. Your existing VTAM printing applictions continue to run without any application changes.
