Fax modems create a file transferable to other fax machines by turning it into
a bitmap.

When you receive a fax on your fax modem, you are receiving a bitmap. When you
send a received fax to a PostScript printer, you are sending it a bitmap of the
page. You could take it in to some word processors as a picture, but you can't
edit it the way you would text.

In order to have it as real text instead of a bitmap, you either (a) retype it
or (b) use OCR software.

Benefits besides editability? Depending on the level of compression your fax
modem uses, a text file might take up less space.
