Upgrade to v2.1 -> Printer don't show any SNMP informetion

I’m in v2, there are no rules defined in this set for " Hosts without system description OID", I’ve enabled sections: printer_alerts, printer_input, printer_output, printer_pages, printer_supply for the folder where my printers are and I don’t have the data …
