snmp - cups snmp backend
lpinfo -v --include-schemes
The CUPS SNMP backend provides legacy discovery and identification of network
printers using SNMPv1. When used for discovery through the scheduler, the
backend will list all printers that respond to a broadcast SNMPv1 query with
the "public" community name. Additional queries are then sent to
printers that respond in order to determine the correct device URI, make and
model, and other information needed for printing.
In the first form, the SNMP backend is run directly by the user to look up the
device URI and other information when you have an IP address or hostname. This
can be used for programs that need to configure print queues where the user
has supplied an address but nothing else.
In the second form, the SNMP backend is run indirectly using the
(8) command. The output provides all printers detected via SNMP
on the configured broadcast addresses. Note: no broadcast addresses are
configured by default.
The DebugLevel value can be overridden using the CUPS_DEBUG_LEVEL environment
variable. The MaxRunTime value can be overridden using the CUPS_MAX_RUN_TIME
The SNMP backend reads the /etc/cups/snmp.conf
configuration file, if
present, to set the default broadcast address, community name, and logging
The CUPS SNMP backend uses the information from the Host, Printer, and Port
Monitor MIBs along with some vendor private MIBs and intelligent port probes
to determine the correct device URI and make and model for each printer.
