File extension prn 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:

Likely can be opened using some older graphics programs only.

How to convert:

Theoretically, it may be possible to convert or export these graphics files to other similar formats, the tricky part would be to find a program capable of doing so.
