HP Web Jetadmin - Impression Counting and HP Web Jetadmin

value of 1. Larger media will have a media size larger than 1, and smaller media will have a media
size smaller than 1.
For devices that don’t support impressions, Web Jetadmin can use Blank Impressions to correlate
values between sheets and impressions. However, the value correlation is only as accurate as the
values HP Web Jetadmin acquires from the device itself. In many cases specific to the device model,
the following formula is true:
Total Duplex Sheets*2 + Total Simplex Sheets – Total Blank Impressions = Total Impressions
This is generally a good rule of thumb when testing HP devices and HP Web Jetadmin counters.
NOTE: Device counts can vary depending on the firmware and implementation.
Column Calculations
The values displayed in the various page counter columns in HP Web Jetadmin are either pulled
directly from the device or are the result of a calculation based upon values pulled directly from the
device. It helps to compare the values seen on a device Usage Page to those displayed under
Web Jetadmin to understand how the values are calculated.
The following screen shots depict the Configuration and Usage Pages for sample devices. The
values on these screen shots will be used in the following spreadsheet to explain how the Web
Jetadmin counter columns are calculated. The spreadsheet includes columns to explain calculations
for three different types of devices: FutureSmart, Oz and LEDM. Examples of FutureSmart and LEDM
devices are as such:
