How to output snmp values ​​for HP printers?

Question

Monitoring

We are slowly introducing Zabbix, in addition to PRTG (the purchased sensors are over, and there is still a lot to monitor). Need to keep track of HP and Kyocera printer consumables.
My actions:
I tear off SNMPv1, public, port: 161
on printers. I add these characteristics for the device to zabbix. A screenshot is attached at the link
yadi.sk/d/hixAcl8hLHiwN It is
monitored and displayed, but the values ​​are somehow strange

c snmp and zabbix just started working, so don't hit hard =)
SNMP OID: 1.3.6.1.2.1 .43.11.1.1.9.1.1
Printer name SNMP OID: 1.3.6.1.2.1.25.3.2.1.3.1 - works fine WITH BOTH printer brands.

Answer 1

The solution was found using Google
Add two items with the desired OID:
1. Cartridge balance (in numerical equivalent): 1.3.6.1.2.1.43.11.1.1.9.1.1
key: usage
2. Cartridge capacity: 1.3.6.1.2.1.43.11 .1.1.8.1.1
key: capacity
And add item c
TYPE: calculated
FORMULA: 100*(last("usage")/last("capacity"))

The result is pleasing to the eye:
yadi.sk/ d/ReTI6ikqLMSAd

Answer 2

there all the counters are constantly increasing - they are of no use except to compare with the resource of the device

The template still needs to be finalized, similar to Kyocer'y, only for these devices the toner level is calculated by the formula.

Here is the result. Now it remains to make the percentage difference.
OIDs are the same for both HP and Kyocera printers
