14 The CUPS SNMP backend provides legacy discovery and identification of
15 network printers using SNMPv1. When used for discovery through the
16 scheduler, the backend will list all printers that respond to a broad‐
17 cast SNMPv1 query with the "public" community name. Additional queries
18 are then sent to printers that respond in order to determine the cor‐
19 rect device URI, make and model, and other information needed for
20 printing.
21
22 In the first form, the SNMP backend is run directly by the user to look
23 up the device URI and other information when you have an IP address or
24 hostname. This can be used for programs that need to configure print
25 queues where the user has supplied an address but nothing else.
26
27 In the second form, the SNMP backend is run indirectly using the
28 lpinfo(8) command. The output provides all printers detected via SNMP
29 on the configured broadcast addresses. Note: no broadcast addresses
30 are configured by default.
31
33 The DebugLevel value can be overridden using the CUPS_DEBUG_LEVEL envi‐
34 ronment variable. The MaxRunTime value can be overridden using the
35 CUPS_MAX_RUN_TIME environment variable.
36
38 The SNMP backend reads the /etc/cups/snmp.conf configuration file, if
39 present, to set the default broadcast address, community name, and log‐
40 ging level.
41
43 The CUPS SNMP backend uses the information from the Host, Printer, and
44 Port Monitor MIBs along with some vendor private MIBs and intelligent
45 port probes to determine the correct device URI and make and model for
46 each printer.
