Why isn the tutorial avialable in PostScript or PDF?
We used to offer a PostScript version of the tutorial, but it caused many more problems than it solved. There were problems with fonts, page size in Europe, older versions of PostScript, and so on. PDF format might solve some or all of those problems, but we also got a lot of complaints about the actual document: “it’s just a PostScript dump of the HTML,” “the links don’t make sense on paper,” and so on. PDF wouldn’t solve those problems. As a result, we no longer provide PostScript, and we won’t be providing it or PDF in the future.
