The printer uses a settings file named global.ini. This file contains settings that will be forced on to all users on the machine. Normal settings are specific to the user, whereas the settings in global.ini applies to all users.
By default the global.ini is located in the folder:
C:\ProgramData\PDF Writer\Bullzip PDF Printer
The last part of the path is the actual printer name it applies to.
On different language specific versions of Windows the name ProgramData may be something different.
