Simple-PDF desktop utility is a standalone PDF creation software. Unlike other PDF software, this one does its magic in one complete neat little package. You do not use it like a printer driver (which is what the competition offers) But you simply fire it up and start using it to directly create PDF files like a mini-DTP system.

You can also use Simple-PDF desktop via a command-line (i.e. without using any graphical interface) to create PDF from some simple instructions written in a text file. If you are a little geeky, you can get other programs to write out those instructions for you and ask Simple-PDF to output the PDF as required. The instructions that Simple-PDF uses are far less complex than the final PDF "instructions" present in a PDF file, as per Adobe's specifications.
