If you use computers long enough, you will probably come to a time when you need to create a PDF (Portable Document Format). PDFs are great for disseminating information in a read-only format (i.e. cases where you just need someone to see a document without being able to edit/change it) with the original formatting intact. What is especially useful is that the person viewing the PDF document only needs a PDF viewer like Adobe Reader or Foxit Reader, both of which are available for free.
The easiest and most reliable software that I have found for creating PDF files is Doro PDF Writer. Once installed, this program will add a printer driver to your computer. You create your document as you normally would using Microsoft Word or Publisher, Corel WordPerfect, or whatever software you like. When you're ready to convert it into a PDF, you use your software's Print capability but select the special Doro PDF Writer printer that has been installed. Once you click the Print button, the Doro software will present you with a dialog box that allows you to choose a location and filename for your PDF file as well as some other descriptive fields about the document itself. You even get the option to open the file in your PDF reader so that you can see if it looks proper before sending it to other people.
One of the other nice features about Doro PDF Writer is the Encryption tab that allows you to encrypt your PDFs with a password during the creation process. Anyone attempting to open the document will need to enter the password before it can be seen in a viewer. Even Adobe's own PDF-creating printer driver cannot add encryption to the document as it is being created. On the down side, the encryption currently used is the 128-bit RC4 encryption of Adobe Acrobat 5.0 (back when it was called Acrobat Reader and not just Reader) and not the more secure 256-bit AES encryption currently used by Acrobat X. On the positive side, however, this does mean that the PDFs created this way can be opened with older versions of the software, and 128-bit encryption is still plenty secure for all but the most sensitive information.
Doro PDF Writer is available for free and works with all recent versions of Windows. Download it and start creating PDF files in no time.
