[Observium] HP mfp m527 and mfp m577 printers

Greetings,

We've just purchased both of these printers. I've started monitoring them with Observium, but all I see under Inventory are the printer itself (hrDevicePrinter) and the printer's hard disk (hrDeviceDiskStorage).

Have I missed doing something, or are these printers just not supported?

This is by no means urgent. I've never tried to monitor a printer before and I just wanted to see what Observium told me about them.

Thanks, - Richard
