Doro PDF Writer by CompSoftDoro PDF Writer is very easy to use and is pretty straightforward. It doesn’t have all the other options that other PDF tools have but it works great in printing PDF files. It is installed as a virtual print driver and converts any printable document or image to PDF format. It can be powerful too as it lets you set the author name and even protect it with a password before conversion. Just select it from the program’s setting menu before printing a PDF document and it will launch and provide you the option to change the document’s metadata. On top of those mentioned is the ability to enable and disable copying, pasting and printing functions of the document. It is compatible with XP, Vista, Windows 7 and 8.
