No, I'm Russian.
At the moment there are two problems with the list of SNMP devices.
1. Not all devices display the NAME (Canon iR2520 and KYOCERA M2535dn). If you change the NAME into the table SNMP of the ocsweb database (instead of NULL, specify any value), then I can see the information about the device, but the next time the device is polled, this value will again become NULL.
2. For HP printers, the name is displayed as NPIEC3BEF, this is the network name of the printer, not the model.
The details of the device show the minimum information (model, IP-address, MAC address, serial number, and number of printed pages)
