PDF Creator allows a PC to create PDF (Portable Document Format) documents from any program on a PC from which you would normally print a paper print. It's a free 'Open Source' project from here http://www.sourceforge.net/projects/pdfcreator
This is not made by Adobe, but rather by a free open source project out at the site SourceForge which houses thousands of other great projects.
PDF readers are free from Adobe, but one normally needs to pay for the tools to make these useful sorts of files, and have many features. However, the above tools create simple PDF files. The 'professional' tools would allow fillable forms to be made, which is a very special funtion few will actually need. So try this one!
The free READER from Adobe is of course also needed.
