Issue:

The PaperPort PDF printer should have installed as part of the paperport installation, but if it didn't or if it was somehow removed, you can install it manually

Resolution:

First, uninstall the existing one, if it's on your system. It is a separate install/uninstall, so you will find it here:

     Control Panel

     Programs and Features

     PaperPort Image Printer (or PaperPort Image Printer 64-bit)

Uninstall it, if it's there. Then look at the location where you unzipped the 14.5 download and you will see a folder called: PPImgPrinter

It has two subfolders:

     System32

     System64

Each of those subfolders has a file in it called:

     setup.exe

Run the setup file for the bit level of Windows that you have (32-bit or 64-bit).   This will install the printer.
