Lexmark printer template edited for Source Technologies ST9730

[jtnfoley]

I've discovered it necessary to edit Alexander Bakaldins excellent Lexmark template to accommodate my Source Technologies re-branded Lexmark monochrome printer.
I'm not sure if this is a difference between Lexmark and Source, a difference between generic and device-specific OIDs, or a bug in the template, but it appears "Imaging Unit Level" (and "Capacity") OIDs have been switched with "Toner print level (black cartridge)" (and "Capacity")

I started with the template template_lexmark_printer-ms826de_(mono) from https://github.com/zabbix/community-...-ms826de_(mono) and immediately got an alarm om the Imaging Unit Level. The absolute (integer) number didn't make sense so I compared it with the printers' web interface, converted Zabbix reported integer numbers to percentages ("("(level/capacity * 100)") and realized the imaging unit life and toner life OIDs were reversed.

I changed a clone of the template and it looks good.

Again, I don't know whether this is a Lexmark to Source issue, a ms826de to ST9730 issue, or simply a bug in the template. I also am new enough to Zabbix that I don't know how to submit template errata, so I figured I'd post here and solicit feedback.

Also, the trigger thresholds seem high relative to the reported capacities of the maintenance kit, toner, and imager. I've adjusted to some lower arbitrary levels for our needs (5% or 10%)
Lastly, I have one printer whose web GUI is reporting VERY low toner remaining, 16 pages estimated, but SNMP is reporting "-3"! I've changed the toner level to a Float as Zabbix doesn't support signed integers and resolved the "snmp string datatype" error in the Zabbix gui.
