I have several HP printers, that are in power-save during out-of-office hours. This gave me error's, so I put these printers on a Week-day Eight-to-Five schedule. This work fine.
Looking at the "Pages Printed" graphs, I only have short "uptime" of the sensor, but I get "the picture" in 2 / 30 / 365 day graphs.
The SNMP-Printer sensor give's me a ton if info. Page-Total count, Toner levels, waste-container levels, etc.
In the live-view, all is well, but in the 2 day / 30 day / 365 day, only Pages-Total count shows meaningfull info. All other counters show <zero>.
I would like historic toner level data.
