You can download, install and activate your copy of NPrinting Server or reactivate an installation that you deactivated to move to another machine after you have obtained a License key and a Control Number.
When you install NPrinting Server, you also install an application called NPrinting Management Console. If you put a check mark in the Launch NPrinting Server box before clicking on the Finish button in the last window (see: Install NPrinting Release 14.x and Later), NPrinting Management Console will start up automatically.
