Monitor in progress print jobs with SNMP

[evanugarte]

I printed a page, then in wireshark I observed the below traffic

request was from my local to printer, response had a source ip of the printer

SNMP	74	get-next-request 1.3.6.1.2.1.43.11.1.1.9
SNMP	86	get-response 1.3.6.1.2.1.43.11.1.1.9.1.1
SNMP	76	get-next-request 1.3.6.1.2.1.43.11.1.1.9.1.1
SNMP	85	get-response 1.3.6.1.2.1.43.13.4.1.2.1.1
SNMP	75	get-request 1.3.6.1.2.1.25.3.5.1.2.1
SNMP	84	get-response 1.3.6.1.2.1.25.3.5.1.2.1

the oid reference below has something about print jobs. this could be useful in knowing if a pdf was printed or not
