KB Home | Printer Support for Hardware Checking using SNMP
PaperCut supports validation of page count analysis using the SNMP counters
on a printer. More information about this can be found in the manual:
Validating Page Counts.
In order to determine the number of pages printed, we look at the difference of the
SNMP page counter before and after the job is printed.
The SNMP standard for printers provides a standard page counter that we use as a fall back
but it does not take into consideration such things as whether the page was color or not.
In order to determine this, we need to look at the manufacturer’s custom metrics which is
expressed in what is called an enterprise MIB.
The custom metrics naturally vary per manufacturer and sometimes vary between the models
of the manufacturer.
As there are a vast number of manufacturers and models of printers, we will need to continually
build up our database of this information and may call upon the customer to help
us gather this information if their printer is not supported.
Q How can I determine if my printer is supported for Hardware Checking?
If the printer is a color printer, then it should, at least,
output the “color_count” for the printer in order to be able to
retrieve how many color pages were printed in a document.
If the only *_count metric is the marker_count, then only basic page counting is supported.
Q How can I help collect SNMP data for my printer in order to send to PaperCut support?
We have developed a command-line tool to interactively guide a user through the process
of performing a sequence of tests which will collect SNMP data.
It will require you to print out some provided sample documents in the directory:
This release contains an updated Java version which no longer supports 32-bit workstations. If you have any 32-bit users launching the User Client or Release Station from a network share, see this Knowledge Base article for more information.
