A lot of devices showing up on the 'Printer out of toner' report.
Example:

Toner: 50/100
Photoconductive Drum: -2/-2
Developer: -2/-2

Information for a couple of devices has been attached.

I have 71 printers claiming they're out of toner, because they show as -2/-3, but under the above mentioned descriptions, -3 can't be out of toner, so that should definitely not be shown in the report.

Also, -2/-2 isn't really helping me much in the report. It basically just translates to "I have no idea how much is left in however much I had in the first case", which kinda makes the report somewhat useless to begin with.

If the purpose of the report is to catch printers running out of toner - any printer reporting "I don't know" or "I don't know, but I'm not empty" isn't really fulfilling the purpose anyway.

My 2 cents.

Filtering out -1 would make sense, though I would keep -2 (though it may be useful to display it as unknown instead of -2).

Those values actually part of the RFC, and have special meanings.

prtMarkerSuppliesMaxCapacity
-1: 'other' = catch all which in practice usually means an error
-2: 'unknown' = the printer does not know the maximum capacity.

prtMarkerSuppliesLevel
-1: 'other' = catch all which in practice usually means an error
-2: 'unknown' = the printer does not know the level.
-3: 'unknown but not empty' = the printer does not know the level, but knows there is some supply remaining.


This is not exactly followed by all MFGs. As an example, the HP 4500 series do not report the capacity, but do detect a 'low' threshold. When a new cartridge is installed, it will report -3. Once the cartridge is below the 'low' threshold (want to say it is 5%), it will return -2. Once the cartridge goes empty, it will return 0.

I think it's safe to filter out the negatives for MaxCapacity?

Is there a way to keep these from appearing on the toner reports?

I've added this request to be included in the next update.

Most likely the printers are not rfc 1759 compliant.
