Notes and Restrictions
The following are the notes and restrictions for using TCP/IP (LPD).
Configuration on Machine
z
IP addresses are managed throughout the entire network system. Configure them
after consulting with your network administrator.
z
Subnet Mask and Gateway addresses may be necessary depending on the network
environment. Confirm with the network administrator and set up the necessary items.
z
When the port status is set to Enable, it sometimes automatically switches to Disable
if the machine has insufficient memory. If this happens, either set an unused port to
Disable, or adjust the assigned memory size.
z
Adjust the receiving buffer [lpd (Spool)] size according to usage. When the receiving
buffer [lpd (Spool)] size is smaller than the transmitted data, the machine may not be
able to receive the data.
Configuration on Computer
z
IP addresses are managed throughout the entire network system. Configure them
after consulting with your network administrator.
z
When performing network settings (IP address, etc.) on a host under the NIS
(Network Information Service) management, consult with the NIS administrator.
Switching Off Power
Check the following points when switching off the machine.
z
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.
z
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.
z
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.
