PDFCreator is good, but ads are annoying. How to block them?
The free version of PDFCreator is configured to display ads, because this is the agreement offered if you choose to install it. However, the only way to remove those ads is by purchasing the Plus version. The Plus version doesn't have ads, it offers fast updates and premium support.
