How to print to PDF in Linux (alternative to PDFCreator, DoPDF, CutePDF Writer, ...)

Add a virtual PDF printer to Ubuntu or other Linux. Just install cups-pdf.

1. Install cups-pdf by running the following in the Terminal:
   

   sudo apt-get install cups-pdf

2. Go to "System" -> "Printing" and hit the New button.
3. Select "Generic CUPS-PDF printer" and hit the "Forward" button.
