Enterprise Server supports LU1 and LU3 printers for use with enterprise servers configured to run IMS applications, and is specifically limited
to printer clients that support the TCP TN3270 protocol. Non-TN3270 printer clients and the IMS Spool interface are not supported.
Before configuring a printer, you must have an MSS-enabled enterprise server defined in
Administration. Once this is in place, do the following:
Enabling Printer Support
The procedure for enabling printer support varies depending on your needs. Consider the following use case scenarios:
- Use Case 1: Most or All Printers are LU1
- No further configuration is required unless some printers are LU3 (see
Use Case 3 below).
- Use Case 2: Most or All Printers are LU3
- In this case, rename the MLU1 printer Term Model definition in the IMSGRP resource group to
MLU3, and redefine it as Term Model specifically for LU3 printers.
Important: You must rename and reconfigure the MLU1 definition, or remove it and create a new definition for LU3 printers. We do not
support multiple Term Model printer definitions for TN32871.
- Use Case 3: Define Specific Printers to
- In this case, you want to install explicit definitions for exceptions to Use Case 1 or 2, or for all printers. This requires
that you add the printer definition or definitions to the IMSGRP resource group by adding a Term definition for each printer.
In addition to defining your printers, you must also configure the following:
- Define the printer to
Enterprise Server security
- Configure your TN3270 emulator to attach to the printer
Assigning Client Names
In the process of configuring printers for an IMS-enabled enterprise server, you must provide a client name and other names
in several areas of configuration. This can be tricky. Consider the following as you complete the configuration process:
- The TN3270 client name is ultimately the IMS LTERM name that identifies the printer.
- This client name must also appear in the
Enterprise Server security system as a user ID. The printer operates under
Enterprise Server with the security authorization assigned to this user ID.
- When attached to
Enterprise Server, this client name appears as the printer's
Net Name on the
Enterprise Server ESMAC
- If this client name/Net Name is not defined to
Enterprise Server with a specific TERM definition, it is assigned the characteristics of the
Enterprise Server TERM model definition with the model name of TN32871.
- The TN3270 printer emulator
Terminal Type definition must default to or be specified as
IBM-3287-1. The TN3270 client name and terminal type are the controlling definitions.
Enterprise Server definitions are used if they match the names specified in the TN3270 client.
