TCP/IP147Problem Solving15Notes and RestrictionsThe following are the notes and restrictions for using TCP/IP (LPD).Configuration on the Machinez IP addresses are managed throughout the system as a whole. The configurationshould be performed only after consulting with your network administrator.z Subnet Mask and Gateway addresses may be necessary depending on the networkenvironment. 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 anunused port to [Disable], or adjust the assigned memory size.z Adjust the receiving buffer [lpd (Spool)] size according to usage. When the receivingbuffer [lpd (Spool)] size is smaller than the transmitted data, the machine may not beable to receive the data.Configuration on the Computerz IP addresses are managed throughout the system as a whole. The configurationshould be performed only 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 the PowerCheck 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 beingprinted is erased. The print data will not be found when the machine is powered onagain.However, if the power was switched off immediately after a computer instructed aprint job, the job may remain on the computer. In this case, the stored data on thecomputer will be printed out in order before any later instructions when the machineis 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 beingprinted is preserved. In this case, the stored data on the machine hard disk will beprinted out in order before any later instructions when the machine is powered backon.z When the [lpd (Spool)] is set to [Off]All print data spooled in the machine receiving buffer, including the data which isbeing printed is erased. The print data will not be found when the machine is poweredon again.However, if the power was switched off immediately after a computer instructed aprint job, the job may remain on the computer. In this case, the stored data on thecomputer will be printed out in order before any later instructions when the machineis powered back on.
