I have recently been frustrated because I don’t have Adobe Acrobate professional on my computer and so have not been able to make PDF files.So a friend sent me to download Cute PDF, a free application which lets you make your own PDFs. Once you install it, Cute PDF is listed as one of your printers: just print to it, and it then asks you for a file name and location for your new PDF file.
My life has become easier.

This is built into OS X, “print to PDF” … never realized that people paid money to do that.
