printer snmp

My Mac uses snmpget and related commands. If installed, you'll find the same commands on Linux. Doing a

snmpwalk -c public hp_printer_ip

returns 245 lines, among which is all the networking info (hardware address, ip, netmask, gateway) and the port it uses:

TCP-MIB::tcpConnLocalPort.0.0.0.0.9100.0.0.0.0.0 = INTEGER: 9100

That info can also tell me how long it has been running, but it doesn't tell me if it is out of paper - I thought that was odd.

On the other hand, asking a Brother printer returns nothing at all, so not all printers support SNMP.

Could you do me a favour?  I couldn't find any useful numbers for the
Xerox N17 printer on their gaudy web pile.  If 9100 works, could you
also check if you can telnet to port 23 and/or 2002?

Tea?  My mom used to make me tea when I got sick.  Now, I drink tea
and I get sick.  Pavlov was right.

One is usually sufficient.  Try this for fun:

getmany printer_ip public iso
snmpstat -s printer_ip

If they support SNMP, they should return some interesting info.  You
get a page count or set an alarm to warn you when it runs out of
paper.  It's also nice for checking the firmware version of
HPJetDirect print servers.
