How to Secure your Web Print Sandbox server

KB Home   |   How to Secure your Web Print Sandbox server

With many thanks to Rhett from Portland State University for this one!

When setting up a PaperCut Web Print Sandbox server we recommend that the machine is physically secure as it is required to be logged in at all times. This can easily be secured by the use of virtual machine software such as VMWare or Virtual Box, to name a couple.

Rhett however emailed in with a very elegant solution using inbuilt Microsoft Windows functionality.

“The system locks so fast that one does not have time to even see a desktop, let alone do anything else, except unlock the desktop.”

Installation instructions

  1. Copy the below batch file contents into your favorite text editor
  2. Save the script to a location on the local machine such as: C:\Windows\System32\GroupPolicy\User\Scripts\Logon
  3. Then use a (Local) GPO to tell the server (workstation) to run the script on logon.

At the moment, after each upgrade of the PaperCut Web Print software I have to go to the start-up folder and remove Web Print shortcut (as the below script will run it for me).
