Printer management software collect printer data like meter readings, toner levels, consumables and printer errors. Data collection is done by a software that gathers info from network printers and sends it over to a central database outside the local network. A software that captures data from the local network and sends it to an external server is usually detected by the antivirus and flagged as malicious software.
Antivirus are updated every 3 hours with numerous changes. When a software that works in the background to monitor printers (aka DCA) is not expressly added in the white list as an antivirus exclusion, it can be blocked very easily. The antivirus can block or even delete the executable files and printers monitoring software will stop reporting. Windows updates, can also block any monitoring software that finds suspicious of spying the net.
