CUPS & snmp autodiscovery

Just did a fresh i686 install on my laptop. kernel 2.6.29, gnome 2.26 etc..

After installing my fav cups front end, system-config-printer-gnome, I noticed that the autodiscovery wasn't working.

I have a x86_64 install at work and running lpinfo -v outputs this:

[12:57 Mars-Arch64 ~]% lpinfo -v
network socket
network beh
network socket://10.55.113.245
network socket://10.55.113.240
network socket://10.55.113.153
network http
network ipp
network socket://10.55.113.250
network lpd
direct parallel:/dev/lp0
direct scsi
network smb

When I run lpinfo -v on my laptop I get this:

network socket
network beh
network http
network ipp
network lpd
direct scsi
network smb

So I did some googling and came across this page http://www.troubleshootingwiki.org/Basi … _CUPS-SNMP
and ran this command CUPS_DEBUG_LEVEL=1 /usr/lib/cups/backend/snmp 2>&1 first on my laptop:

bash-3.2# CUPS_DEBUG_LEVEL=1 /usr/lib/cups/backend/snmp 2>&1 | tee cupssnmp.log
DEBUG: Scanning for devices in "public" via "@LOCAL"...
DEBUG: 0.000 Sending 46 bytes to 10.55.113.255...
DEBUG: 1.001 Scan complete!
bash-3.2#

Then I ran it on my desktop:

[13:03 Mars-Arch64 ~]% CUPS_DEBUG_LEVEL=1 /usr/lib/cups/backend/snmp 2>&1

So something is wrong either cups or smnp discovery.    No idea where to go from here...

Re: CUPS & snmp autodiscovery

Yes, the desktop computer running x86_64 is running on the same network.   It can see the printers, my laptop cannot.   btw tried both on wireless & wired.  Same result.
