The point is that this is the less likely event of the two, in the
situations I have seen. In addition, PostScript printers are currently
vastly more widely available than Python or Cairo printers, of which I
have seen none so far. So, you can often print PostScript directly.

I hope they are great. I want to make one thing clear at this point:

There are several well-known shortcomings of PostScript, and they are
likely especially well-known in this newsgroup. However, the existence
of other tools for different tasks definitely isn't one of them, and
even less so when they cannot, either in principle or due to their being
less widely available or their not being available at all in the
situations where PostScript *is* available, subsume it. For example, a
comparatively limited page description or XML format cannot replace a
Turing-complete programming language due to inherent reasons. As another
example, a language that is not well supported by other tools in which
PostScript is well supported and where I need its functionality cannot
take the position of PostScript either. I am thinking for example of
LaTeX etc., where I frequently embed PostScript files, but not Cairo.

All the best,
Markus
