Any time you use a computer to create a printable document, it can be considered desktop publishing.
The term, however, is most commonly used to refer to professional computer-based publishing.
Publishers may also use programs like Adobe Photoshop and Illustrator to create printable images. Even word processing
programs like Microsoft Word can be used for basic desktop publishing purposes.
Complete desktop publishing involves the combination of typesetting (choosing fonts and the text layout), graphic
design, page layout (how it all fits on the page), and printing the document.
