How to open, edit or print the "print to file" generated prn format document

When we print the file, we will see an option to "Print to file" in the print dialog box. If you check this option to print, a document in prn format will be generated. So how do you open, edit, or print this prn-formatted document? In fact, the prn file is not a fixed format. It is composed of printer print commands. Different printer drivers produce different files. Such files generally cannot be opened or converted to other formats. If you want to print this prn file, just enter the command “copy file name.prn prn /b” at the command prompt.
