SNMP and mibs?

["Jan Johansson" <jan.johansson@se.nyklogistics.com>]

I have the following components on a debian system

hooch:/usr/share/snmp/mibs# dpkg -l | grep snmp

I have downloaded printer.mib from mibdepot. Renamed the file from
mib->txt, copied it to /usr/share/snmp/mibs, deleted the .index file.

Yet, snmpwalk gives me (among others)
.iso.org.dod.internet.mgmt.mib-2.43.7.1.1.4.1.9 = INTEGER: 2004 when
querying a HP-printer. 

Why isnt the printer mib being used? What am i missing here?
.1.3.6.1.2.1.43 should be "printer mib"?
