Setting Up and Managing the LPR/LPD Print Service
22.2 Configuring LPR/LPD
Table 22–1 (Cont.) LPD Logical Names
Logical Name Description
TCPIP$LPD_RCV Writes diagnostics to the receiver log file
TCPIP$LPD_RCV_LOGFILE.LOG. Applies to
inbound jobs (LPD server) from the time they
are received from the remote host over the
network to the time they are queued to the
local print queue for processing by the LPD
print symbiont.
TCPIP$LPD_DEBUG and TCPIP$LPD_RCV
are bit-mapped values. The low-order three
bits turn on all diagnostics generated by either
the sender or the receiver.
To define these logical names, set the following
bits in the value:
• Bit 0 indicates minimal debugging
information.
• Bit 1 indicates an intermediate amount of
debugging information.
• Bit 2 indicates the full amount of
debuggging information available.
• Bit 3 logs the actual data sent and
received over the network.
If you set the fourth bit, the LPD symbiont
logs each buffer that it sends over the TCP/IP
link, and the LPD receiver logs each buffer
that it receives from the TCP/IP link. The
log files let you see exactly what the LPD is
sending (for outbound jobs) and receiving (for
inbound jobs).
To set the fourth bit, enter:
$ DEFINE /SYSTEM LPD_RCV 8
$ DEFINE /SYSTEM LPD_DEBUG 8
For more information about using these logical
to solve printing problems, see Section 22.8.
22.2.1 LPD Server Startup and Shutdown
The LPD server can be shut down and started independently of TCP/IP Services.
This is useful when you change parameters or logical names that require the
service to be restarted.
The following files are provided:
• SYS$STARTUP:TCPIP$LPD_STARTUP.COM allows you to start up the LPD
server independently.
• SYS$STARTUP:TCPIP$LPD_SHUTDOWN.COM allows you to shut down
LPD server independently.
