snmp - cups snmp backend (deprecated)
lpinfo -v --include-schemes snmp
The DEPRECATED 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
lpinfo(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 /usr/local/etc/cups/snmp.conf configuration
file, if present, to set the default broadcast address, community name, and
The CUPS SNMP backend is deprecated and will no longer be supported in a future
version of CUPS.
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.
