Logical Printer A logical printer acts as a filter between the network and the physical
printer. It appears to the user as a normal printer with additional
characteristics. For example a UNIX workstation may only send a line
feed (LF) to a shared printer that needs carriage return (CR) and LF.
The logical printer can solve this problem by adding a CR.
LPD Line Printer Daemon protocol. A print server protocol widely used on
the Internet.
LPR Line PRinter. The Unix print command. This does not actually print
files but rather copies or links them to a spool area from where a
daemon copies them to the printer.
LU Logical Unit. The user's port into an SNA network. LU1 is a high
performance print stream. LU2 is a 3270 terminal data stream. LU3 is
a 3270 print data stream. LU6 is a host-to-host data exchange
stream. LU7 is the 5250 terminal data stream.
LU6.2 IBM Peer-to-peer data stream for NOS functions. Supports
asynchronous (store-and-forward) networking.
MIB Management Information Base. A database of network configuration
information used by SNMP and CMIP to monitor or change network
settings.
NAU Network Adressable Unit. Entities within an SNA network (SSCP, PU,
LU) that can send or receive requests and responses. An SNA network
is made up of NAUs and the underlying path control network.
NCP NetWare Core Protocol. Network clients use the NCP to request
services of servers, and servers use NCP to provide services, such as
file and print services.
