ABSTRACT:
A printing apparatus comprising an outer case having a cylindrical inner surface, an inner case inside the outer case and having a cylindrical outer surface facing and spaced by a predetermined distance from the cylindrical inner surface of the outer case; a paper path formed between the inner surface of the outer case and the outer surface of the inner case; a paper feed unit feeding a sheet of paper along the paper path; a printing unit rotatably mounted inside and about a central axis of the inner case; and a rotating unit rotating the printing unit. The length and width of the printing apparatus is less than the length and width of the sheet of paper, thereby providing true compactness and portability without sacrificing print quality. Continuous rotating printing unit provides significant increase in print speed without sacrificing print quality.
