For the BIND sent to start a session with a Network Print Facility logical printer, there are some parameter restrictions. The LU Type parameter must be consistent with the type of print data to be sent during the session, and the FM Profile and TS Profile values must be allowed for that LU Type. Valid combinations of these BIND parameters are shown below:

Each BIND specifying an LU type of 0 or 3 must also specify a valid non-zero screen size.

In VTAM®, various sets of default BIND parameters are defined by entries in user-modifiable logmode tables. Either explicitly or by default, the APPL definition for each Network Print Facility logical printer is associated with one of these logmode table entries containing a specific set of BIND parameters. When starting a session, the PLU uses these default BIND parameters, or it uses its own resource definitions to override some or all of the default BIND parameter data.

Attention: When an IMS™ application is the PLU and the logical printer is defined in IMS as a non-SNA 3270 device, IMS uses the default BIND parameters without any changes. Therefore, those default parameters must be correct for a 3270 data stream as illustrated in Table 1.

In most other cases, CICS® and IMS subsystems override default BIND parameters as necessary to ensure consistency. With session partner LUs other than CICS or IMS, make sure that the combination of default BIND parameters in the logmode table and parameter overrides by the PLU result in a correct BIND for the Network Print Facility.
