Back in 2020, PaperCut released <a href="https://staging.selectec.com/papercut-20-0/">version 20.0 of PaperCut MF</a>. This update introduced "Automatic Application Server failover"; a new in-app solution to protect the PaperCut Application Server Layer, where clustering or virtualisation technologies cannot provide failover. To do this, you need a Network Load Balancer (hardware or a virtual appliance) to provide automatic failover at the PaperCut MF Application Server layer.
