Maybe I should add:
* SNMP autodiscovery does not mean "auto-installation" of printers;
however, it reduces installation of newly discovered devices to
a simple two click process in most cases.
* Currently, the SNMP autodiscovery is run every time you open or
reload the CUPS web admin page (http://localhost:631/admin/).
* You can run the snmp autodiscovery also from the commandline, by
typing "/usr/lib/cups/backend/snmp" (or, if you use Ubuntu, this
variant: "/usr/lib/cups/backend-available/snmp"), and then use
the info displayed (IP address of printers, model names) in an
additional "lpadmin -p printername ..." command to install them.
* If you use KDE and its "kaddprinterwizard" utility, when you use
"Other printer types" on the "Backend Selection" page, you'll see
all potential "device URIs" (that were discovered) listed amongst
the generic ipp, http, lpd and socket URI schemes (this is true
for KDE 3.5.3, but should work for older versions as well).
* You do not need to configure your printers
* You do not need to run it when you remove a printer
* In the web interface you can choose if you want to install what
it found -- but you can't override what backend or printername
it suggests... (you could remember the IP address and model name
it displays, and re-use that info with any other method of
printer installation you prefer.
Cheers,
Kurt
