A.5 Precautions and Limitations 143
TCP/IP (LPD)
Precautions and Limitations in TCP/IP (LPD) are as follows.
Printer Settings
• Pay attention to the IP address settings. The IP address is managed by the overall
system. Consult your network administrator to configure the settings.
• Depending on the network environment, you need to set the Subnet Mask and Gateway
Address. Consult your network administrator and configure the required items.
• If the memory is insufficient when the port is enabled, the port may be disabled
automatically. In this case, disable the port(s) that are not in use, change the memory
allocation or increase the memory.
• Set the size of the receive buffer [LPD Spool] according to your environment. The printer
may not be able to receive data if the size of the receive buffer [LPD Spool] is small than
the sent data.
Computer Settings
• Pay attention to the IP address settings. The IP address is managed by the overall
system. Consult your network administrator to configure the settings.
• Consult the NIS administrator when configuring network settings (such as IP address) on
computers under NIS (Network Information Service) management.
Switching Off the Power
Take note of the following points when switching off the power of the printer.
When [LPD Spool] is set to [Memory]
Data spooled to the printer memory, including those that are being printed, will be deleted.
Print data will be lost when power is switched on.
However, if the power is switched off immediately after sending the job, the print data may
be saved on the computer. In this case, print data that was saved will be printed first once
the power is switched on even if a new job has been sent.
When [LPD Spool] is set to [Hard Disk]
Data spooled to the printer hard disk, including those that are being printed, will be deleted.
Print data that was saved will be printed first once the power is switched on even if a new
job has been sent.
When [LPD Spool] is set to [Off]
Data spooled to the receive buffer, including those that are being printed, will be deleted.
Print data will be lost when power is switched on.
However, if the power is switched off immediately after sending the job, the print data may
be saved on the computer. In this case, print data that was saved will be printed first once
the power is switched on even if a new job has been sent.
