Take maximum care with the IP address settings. IP addresses are managed throughout
the system as a whole. The configuration should be performed only after consulting with
your network administrator.
When performing network settings (IP address, and so forth) on a host under the NIS
(Network Information Service) management, consult with the NIS administrator.
When the lpd (Spool) is set to Memory.
All print data spooled within the machine memory, including the data which is being
printed is erased. The print data will not be found when the machine is powered on again.
However, if the power was switched off immediately after a computer instructed a print
job, the job may remain on the computer. In this case, the stored data on the computer will
be printed out in order before any later instructions when the machine is powered back on.
When the lpd (Spool) is set to Hard Disk.
All print data spooled in the machine hard disk, including the data which is being printed is
preserved. In this case, the stored data on the machine hard disk will be printed out in order
before any later instructions when the machine is powered back on.
When the lpd (Spool) is set to Off.
All print data spooled in the machine receiving buffer, including the data which is being
printed is erased. The print data will not be found when the machine is powered on again.
However, if the power was switched off immediately after a computer instructed a print
job, the job may remain on the computer. In this case, the stored data on the computer will
be printed out in order before any later instructions when the machine is powered back on.
When the lpt (Spool) is set to either Hard Disk or Memory.
If the transmitted print data size exceeded the available amount of either hard disk or
memory, the print data will not be received.
Note
When the print data has exceeded the receivable size, some computers may immediately
re-transmit the print data. When this occurs, the computer appears to be halted. Deal with
this problem by canceling the print data transmission from the computer.
When the lpd (Spool) is set to Off.
While the machine is receiving a print request from a computer, the machine cannot accept
any print requests from other computers.
When the IP address of a computer or a computer name is changed.
When the IP address of a computer or a computer name is changed, queries and chancel
processes from the machine will not be performed correctly. Switch the machine off and on
when there is no print data in the receiving buffer.
