This is caused by the http_inspect preprocessor. This preprocessor
analyzes at least part of your HTTP traffic. It found a uri in an http
request where the directory string was longer than the maximum
http_inspect: oversize_dir_length

Your printer is configured to send out SNMP Broadcast Traps. If you do
not use any software that listens to SNMP Traps I would advise disabling
it. If you do, you might want to remove Signature 1416 in Snort
alert udp any any -> 162 (msg:"SNMP broadcast trap";

Well depending on the value you used for oversize_dir_length and your
webserver it might be normal or unusual.
