Communicating with the channel-attached host
A system that is channel attached to a host can receive data from
the host in online mode. Before data can be sent to the printer,
both the printer operator and the host operator must issue
commands to place the LPS online to the host.
All system operations and maintenance tasks can be performed
while the printing system is online. However, you may be asked
to take the system offline for service or other purposes, and to
bring it back online when ready to resume operation.
Placing the LPS online
Follow these steps to place the LPS online:
1. Enter ONLINE.
The system responds by displaying:
OS0030 System is “ON-LINE”
OS1000 READY FOR COMMANDS
2. Enter START and begin normal job processing.
Until a START command is entered, the LPS is in an online
but not ready state, and the host does not transmit any data.
3. Request the host operator to vary the system online.
For more information on starting print jobs, refer to the
“Printing jobs” chapter.
Taking the LPS offline
