What is prn file? How to open prn files?

File type specification:

Bitmap image file type icon Bitmap image file type

The PRN file extension is used for raster graphic files, used in Calcomp  plotters and digitizers. Seems like very old graphic file format, probably no longer used. Calcomp shut down all of its operations in 1999.

A .prn file is a bitmap in black and white, or 4bit CMYK.

Help how to open PRN files:

This file type is not meant to be opened directly, there is no software that could open and work with it directly, or there is no information available in public sources about opening this file type. This is usually the case of some internal data files, caches, temporary files etc.

How to convert file with extension PRN:

As far as we know, this .prn file type can't be converted to any other file format. This is usually the case of system, configuration, temporary, or data files containing data exclusive to only one software and used for its own purposes. Also some proprietary or closed file formats cannot be converted to more common file types in order to protect the intellectual property of the developer, which is for example the case of some DRM-protected multimedia files.
