Subject: [PATCH] Let snmp backend also use manufacturer-specific MIBs

… of HP and Ricoh to obtain the device IDs of network-connected
printers. This way we get more reliable information about make and model
and in addition the supported page description languages, which allows one to
identify whether an optional PostScript add-on is installed or for an
unsupported printer which generic PPD is the best choice (requested by
Ricoh).
