In information handling, a hard copy is a permanent reproduction, or copy, in the form of a physical object, of any media suitable for direct use by a person (in particular paper), of displayed or transmitted data. Examples of hard copy include teleprinter pages, continuous printed tapes, facsimile pages, computer printouts, and radio photo prints.

Magnetic tapes, diskettes, and non printed punched paper tapes are not hard copies.

Soft Copy

A soft copy is the unprinted digital document file. This term is often contrasted with hard copy. It can usually be viewed through an appropriate editing program, such as word processing programs, databaseprograms, or presentation software, depending on the file type.

It can be transported from one computer to another through file transfer/downloading mechanisms such as ftp or http, as an email attachment, or through USB drives and other disk drives. Keeping a digital copy of adocument can allow easy editing of it later on. See hard copy for information about printed documents.
