Yes, I suppose there could be an fully ASCI text ready .prn file, but every
printer sold today needs lots of printer control codes in the .prn file so
that the file is unreadable when opened with any text editor. Word can not
handle the undisplayable bytes which normally occur.
The .prn file produced by a printer driver program is unique to the printer.
I doubt there is any printer made for at least 10 years that uses a
completely ASCII text .prn file.
A Post Script based .prn file is made of bytes that are also all displayable
characters, but many are printer control codes. It is still useless when
opened with Word. (I suspect that is why they experienced such a large file.
Word 200 produces ridiculously large PS files.)
Anyway, that wasn't the point of my e-mail. The point is that a .prn file is
never the proper way to share information with someone else. They should
share the source .mbl file. If they want to separate out a portion of the
file or combine files without using DeedMapper to edit it, they can use
WordPad or NotePad to delete or combine portions. It is not a good idea to
use Word for this. It could mess you up, for example, by adding carriage
returns into long lines.
