Not getting complete Printers info

Some model printers don't report everything you think they should or would. Even with all the correct settings. Some of the cheaper networked printers don't even have a way to setup SNMP. Also local printers IE: USB with print agent for reporting, plus the ability of the local driver talking with the print agent will only just send the hostname of the printer, (actually the hostname of computer it's connected to,) and pages printed, but not the toner levels.
