pfSense Vouchers Printer is an easy way to print vouchers from Captive Portal.
This is a small application that is based on Access, you don't need Access installed on your machine to run the APP, but it only works on Windows environment.
You just have to download the ZIP file, uncompress it, run the setup file, and it's done, if you prefer, you could burn it on a CD or DVD to use later.
Once you installed the APP, run it and import the CSV files that you get from Captive Portal in pfSense, you need to write the value in minutes as the CSV file doesn't have that information on it.
After that, you could print vouchers in two ways: one by one or several at a time.
This application is free and doesn't have any restriction on use, nor the author assumes any responsibility for its use as well. At least for now, it will not be given any assistance.
Meanwhile, if you like the application you can always contribute with a donation, or at least you could click in some of the advertising links.
Thank you, enjoy...
