PRN format can be created when you choose the "Print to File" option within the Print dialog box. Typically, files of this format contain text and other content, as well as instructions for the printer. PRN is much like PS file, only it can viewed with a limited number of programs. They are: ACD Systems Canvas 12, Microsoft Office Document Imaging, AllWeb FastPrint, Microsoft Windows Command Prompt, and Free Raw Print (FRP). If you want to view PRN files with Internet browsers, you should consider converting PRN into XHTML, a reformulation of HTML 4 as an XML 1.0 application.
