I've enabled SNMP traps on my HP LaserJet 4100N and added the
LaserJet_Series_4100-MIB MIB to my /usr/share/snmp/mibs directory
under Fedora Core 3. I set my MIBS environment variable to ALL. When
I run snmptrapd I get lines in /var/log/messages that look like this:

Apr 11 15:44:00 myhost snmptrapd[10415]: aaa.bbb.ccc.ddd: Enterprise
Specific Trap (.40050) Uptime: 1 day, 14:45:22.51

("myhost" is the name of my machine and "aaa.bbb.ccc.ddd" is the IP
address of the printer.)

What do I need to do to get messages in a human-readable form (e.g.
"The printer was power-cycled.")?
