PaperCut NG & PaperCut MF Manual


Technical overview

The goal of the Site Server is to support access to printing and copying, and is designed to be implemented with equal ease for existing PaperCut customers and new PaperCut Customers. The diagrams below highlights the change in design for existing customers implementing a Site Server, or for new customers that want to incrementally build a solution and phase a Site Server in after a basic single server solution is functioning.

Figure 10: WITHOUT Site Server

Figure 11: With Site Server

These images show the changes in how elements of a PaperCut solution communicate when a Site Server is deployed.

  • MFDs now communicate with the Site Server. This ensure an outage between Site Server and Application Server is defended by the Site Server.

  • Print servers also communicate with the Site Server when the Application Server is unavailable.

During normal operation where the Site Server and the Application Server are connected, the two servers together deliver the full set of PaperCut functionality. In anticipation of an outage, the Site Server also caches an up to date set of Application Server data.

In the unlikely event of an outage, the Site Server immediately takes over to deliver business continuity. When the link is re-established, normal operation resumes and offline job logs and transactions are submitted to the Application Server.

What you will need

The Site Server implements the core functions of the Application Server, and as such the majority of requirements are the same.

Where to deploy

An effective way to consider where to deploy PaperCut Site Server is to install a Site Server in any network segment where you have concerns about the link reliability between this segment and the Application Server where an outage to this segment would impact your business.

  • Remote sites

  • City offices

  • Separate campuses

  • Individual buildings with poor links

  • Local sites where servers are on the Private Cloud
