► Print the file and a default file with PRN extension can be seen accompanying the actual file. But do you know how to use it? This Techspirited article will help you know what a PRN file is and how to open it. You must have seen or heard about this file extension. With a PRN file, printing was all the more easy, as this file could translate the directions of the user and transfer them to the printer. In the late sixties, the laser printer was invented. But then came the Xerox machine, which could develop copies of a particular file. However, there was no one device that could do both. Then came plotting, which used to cut vector shapes with the help of a stylus blade. The next step in the evolution was the dot matrix printer, capable of printing grayscale graphics. The earlier devices could print out ASCII characters and text. Then came the PRN format, wherein the file contains the text to be printed and the instructions for a printer. Before the printer could print out color or B/W, everything had to be done through code. The desktop publishing industry has undergone many changes. PRN can be used as a filename regardless of the extension.
