If the model name of the printer is the same as the assetname of the printer, this is likely what is being retrieved through SNMP for the printer. Likely, SP8200DN is the name of the printer in SNMP. Do note that duplicate assetnames are not an issue for non-Windows assets, printers are
uniquely identified based on their MAC address within Lansweeper (if found). In your case it's possible that the full DNS name of the printer is being retrieved, which would contain IFNP032, however, this information is not used to form the assetname if a name can be retrieved through SNMP, as the name in SNMP *should* be more accurate than a partial string selection of the DNS name.
In this situation the only solution would unfortunately be to manually rename the printers and to lock the asset name against scanning.
