Appendix C: I/O Port Polling
❖
C-3
Except for those on the LocalTalk interface,
print jobs are
processed in the sequence in which they are received by the
printer
. As soon as one print job has finished, the printer
continues polling until it finds another port that has received
data.
If a print job is incomplete, the printer waits until the port is
inactive for the
Port Timeout
period. After that, the printer
ends the incomplete job and continues polling the ports when
either:
•
Auto Job End
is
On
or
• Another print job is received on a port
Therefore, the printer does not excessively service one
particular port.
You may set the
Port Timeout
period and
Auto Job End
on
the Control Panel or with the RUI. For additional information
on
Port Timeout
or
Auto Job End
, either see
Chapter 3: Using
the Control Panel
, or refer to the
Document Services for
Printing Guide
.
Port Polling With a Hard Disk Installed
When a hard disk is installed, the printer can spool print jobs
from the parallel and serial ports. The print jobs are spooled,
without any processing, onto the hard disk. Jobs are then
processed in the order in which they were received.
