PDF and Postscript

Based on Adobe's PostScript, PDF files are widely used for sending documents to commercial printing houses. Whereas PostScript was designed as a language to drive the printer and imagesetter hardware, the PDF format enables users to view and interact with the document. At the commercial printer, the PDF file is converted to PostScript for printing.
You can turn your RTF documents into PDF with the help of RTF TO XML converter.
