LU0-DSC mode is utilized when no host printing controls are required
to accomplish the print function desired and the control unit is attached
by a VTAM-Controlled NON-SNA Control Unit. An existing local 3174 NON-SNA-connected
control unit is assumed. The steps required to install an LU0-DSC printer
for host definitions are as follows:
Define to VTAM by adding logmode entry to VTAM Logmode Table
Define to JES2 (Not required but recommended. See details below)
Define to CICS or another Application Program such as VPS or JES328X products.
Select the options on the printer that are appropriate for the environment.
VTAM Definition
The following should be added
to the Local Major Node VTAM definition. The printer will be attached as an
LU1-IPDS capable printer.
LOC3174 VBUILD TYPE=LOCAL
LOCPU74 PU CUADDR=nnn...
LOC6500 LU
LOCADDR=n,MODETAB=MYMODETB,DLOGMODE=printer,ISTATUS=ACTIVE
The following entry should be placed in the VTAM MODE TABLE
specified above or another of your choice.
Host
commands for changing printer settings are not supported in this mode. Refer
to the vendor documentation for defining an DSC printer to the program for
its use.
Printer Settings
It is recommended that the
following printer settings be changed from factory default setting:
v Printer Control => Interface Selection => Coax
Coax Interface => Format Control => Enable
Coax Interface => Early Print Complete => Enable
In LU0 mode the printer settings control the orientation, CPI,
LPI and all other aspects of the printed output. Therefore, you must set the
printer settings to match the characteristics of the job you are printing.
Host controls are not supported in this mode.
