Abstract
A fixer includes a fixing roller around which a recording medium is directed such that the print image to be fixed faces toward the shell surface of the fixing roller. A fixing gap is generated with a gaseous fixing medium between the shell surface of the fixing roller and the recording medium. This advantageously produces an efficient and gentle fixing of the print image.
