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
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 environment variable.
The SNMP backend reads the /etc/cups/snmp.conf configuration file, if
present, to set the default broadcast address, community name, and
logging level.
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.
