IPDS for Control Units
Figure 26. LU-1 Data Stream Modes
Implicit Termination of IPDS Mode
If IPDS mode is active, any of the following causes termination of the active
destination selection and is an implicit termination of IPDS mode:
•
A chain indicating End Bracket (EB)
•
CLEAR
•
Power-on-reset (POR).
Note: IPDS always returns to the home state upon termination.
Copy Considerations
Because an End Bracket is also an implicit termination of IPDS mode,
between-bracket printer sharing can be used for either operator-initiated or
host-initiated copy operations.
For improved throughput, the recommended procedure is to include the entire
page within a chain.
