That's very good news.

That must be what Joe Smith was talking about.

They are still programming languages of a sort. And PS is considerably
more complex than HTML, because it contains all sorts of instructions
to the printer.

What a printer can deal with is much simpler HTML than a browser can
deal with, obviously.
This is simple to write by hand. I do it all the time.
It seems to me that the first step in such a program would be to convert
the HTML source to HTML 2.0, (or thereabouts) and then to convert it to PS.
By-the-way: Keith Thompson <kst-u@mib.org> says that a perl2C program exists....
(and is arrogant enough to think I will take his word for it even though
it came packaged in another of the attacks the creep loves to launch.

I use bash for a scripting language. Works fine.
