Installing Cups-PDF to Ubuntu
You can easily add a PDF distiller to Ubuntu which will enable you to create a PDF file by “printing" the contents of your document, image or other printable document. Cups-PDF creates a new virtual printer on your system, and uses this to generate the portable document.
There are two ways to install Cups-PDF, either via Synaptic (System > Administration; search for “cups-pdf") or via the Terminal (Applications > Accessories), where you should enter
sudo apt-get install cups-pdf
Both methods will require your password, and once this is entered the PDF distillation software will be installed in a matter of seconds. Once complete, navigate to your Home folder (quickly opened via Places) and create a New folder (most quickly done by right-clicking) called PDF (make sure you use upper case characters).
After you have done this, you will then be able to create a PDF document in Ubuntu. For instance, if you have an image that you wish to save in portable format, simply open it, select File > Print and find the new printer called PDF. With this printer selected, use the Print button to create the document, which you should find a few moments later in Home/PDF.
