Description:
	1) Connects to printers and reads its
		predefined values via SNMP.

	2) Reports values to URL.

Values:
	Name, S/N, Prints, Toner, ...

	[!] -1 means no value on OID; usually happens
		if a printer doesn't support the
		  requested function
	[!] -404 Timeout
	[!] -401 Unhandled Exception
