pdfMachine is a $49 PC app for generating PDF files:
Our pdf writer pdfMachine converts a print stream from an application directly into a PDF. Once you have installed the pdf writer, open your document that you want to convert, then click “print”, select the “Broadgun pdfMachine printer” and that’s it!
A free, Lite version, PDFMachine White (rather odd choices of names) offers basic functionality.
Except that this functionality has been a basic built-in part of Mac OSX since it was released- all print dialog boxes for any document have an option to save as PDF. I use it for 99% of my PDF creation.
