I recently read the following:
"IntrePress treats each page as an entity unto itself. No command or
statement from one page can affect another. This is possible in
PostScript, but isn't manadtory. This unique InterPress feature allows
you to print a document with the pages out of numeric or sequential
order. It is a terrific feature if you're printing duplexed pages on a
laser printer."
How does this work in PostScript, and do all laser printers understand
this parameter? If not, what do they do with it?

If not, what do they do with it? PostScript has a *convention* that allows you to do this. It's called the "structuring convention" and it allows you to structure a document using comments into a prolog and separate pages. If done correctly (see devps or TranScript for programs that produce structured PostScript files), the file can be split into separate jobs, reversed, pages selected, etc. The only drawback with this is that programs that don't conform to this convention can't be handled properly. Obviously, there's a double-edged sword here: PostScript gives you lots of flexibility in how your pages can be set up (you're not *restricted* to someone else's idea of page interdependence as you are with InterPress), but at the same time, you have to make a special effort (as must any postprocessors) to make your pages independent of each other. I prefer having the flexibility myself, as there are times when pages simply have interdependencies.
