PostScript (PS) is a page description language (a Turing complete programming language) in the electronic publishing and desktop publishing business. It is a dynamically typed, concatenative programming language and was created at Adobe Systems by 1982 to 1984 (Wikipedia).
Any Morph (including Worlds or BookMorphs) can be saved as a Postscript file. BookMorphs become multi-page PS files, others get saved as EPS files.
Postscript rendering works again with current default fonts
