Notes and Restrictions for Using TCP/IP
This section describes notes and restrictions to observe when using TCP/IP (LPD).
Configuration on the Machine
z
IP addresses are managed for the entire system. Configure the settings only after
consulting your network administrator.
z
The setting of subnet mask and gateway addresses may be required depending on
the network environment. Consult your network administrator and configure the
required settings.
z
When the port status is set to [Enabled], it may automatically switch to [Disabled] if
the machine has insufficient memory. In this case, either set an unused port to
[Disabled] or adjust the assigned memory size.
z
Adjust the receiving buffer size for LPD in [Receiving Buffer - LPD] according to
usage. If the receiving buffer size is smaller than the transmitted data, the machine
may not be able to receive the data.
Configuration on the Computer
z
IP addresses are managed for the entire system. Configure the settings only after
consulting your network administrator.
z
When setting the network such as IP addresses with a host used under the Network
Information Service (NIS), consult your NIS administrator.
Turning Off the Machine
Check the following points when turning off the machine:
z
When [Receiving Buffer - LPD] is set to [Spool to Memory]
All print data spooled within the machine memory, including the data which is being
printed, is erased. The print data does not remain when the machine is turned on
again.
However, if the machine was turned off immediately after a computer instructed a
print job, the job may remain on the computer. In this case, when the machine is
turned on, the data stored on the computer is printed before any jobs instructed
subsequently.
z
When [Receiving Buffer - LPD] is set to [Spool to Hard Disk]
All print data spooled in the machine hard disk, including the data which is being
printed, is saved. In this case, when the machine is turned on, the data stored on the
machine hard disk is printed before any jobs instructed subsequently.
z
When [Receiving Buffer - LPD] is set to [No Spooling]
All print data spooled in the machine receiving buffer, including the data which is
being printed, is erased. The print data does not remain when the machine is turned
on again.
However, if the machine was turned off immediately after a computer instructed a
print job, the job may remain on the computer. In this case, when the machine is
turned on, the data stored on the computer is printed before any jobs instructed
subsequently.
