How to Print a PRN File

A .prn file is a binary file that contains all of the formatting codes necessary for the document to print properly. The Windows print-to-file feature allows you to send a document to a file for future printing. When the print-to-file option is selected, you are prompted to enter a location and file name, and the file is saved with the .prn extension. This can be handy when the printer is offline or temporarily unavailable. Printing a .prn file requires the use of the command-line window.
