If you re-package this, you will likely end up with all the files installed but no 'printer' appearing for users to use.
Plus, if you use a blank, sacrifical packaging machine, you end up with the driver using port NE00: which most users will already be using. You then have the pain of adding a CA to loop through the installed devices and ports to find the next one available, etc, etc.
Instead, simply wrap the vendor's installer but add the 'silent switch:
"INSTALL PDFR" /S
For uninstalling, use UNINSTALL.EXE which gets installed to INSTALLDIR with the same switch:
You *MUST* use upper-case 'S' or the switch is ignored.
Also, both EXEs are multi-threaded and so will exit back to your command prompt (or whatever) immediately, so you would be best to wrap that call in a script which uses WMI or similar to test if the process exists or not.
Note also that the uninstaller doesn't remove the shortcuts nor does it remove INSTALLDIR. You'll need some script to do that.
