 The quality of the text composition produced by Hz-program, together with the lack of details of its inner working, created some mythology about it.Zapf greatly contributed to this, claiming to have reached the same level as Johannes Gutenberg.The particular technique of condensing and expanding characters (glyph scaling) which is an essential part of the Hz-program, and which is now an option in Adobe InDesign and pdfTeX, has aroused critique from well-known designers like Ari Rafaeli.
