When I'm back on my main machine in a week, I'll correct the webpage. Thanks.

1. With old PostScript font names, you may be looking for slightly crippled file names – 'UnivCondIta' or whatnot.

2. Taking another look at the graphic you posted suggests that the font is _not_ Univers – which has an angled top of the t as well as a slightly less round look. Instead I'd guess that font replacement just uses a (fake) narrow Helvetica there. And, indeed feeding your app with easily recognisable Helvetica chars (G, R) confirms that guess.

The command line I tried: locate Univers | grep -vF Universal.

Are you sure you don't have a copy of Univers sitting _somewhere_ (X.5 is rather good at finding fonts in remote locations and using them). I can't reproduce the behaviour here.

I don't have a ruler in the office, but what's the chance of fitting the printout (diagonally?) on a sheet of A3? Would reduce the possibility of 'Fail'.

I just tried it in Lineform. It fits diagonally, but just barely. You'll need a printer capable of borderless printing, as well as a vector editor (such as Lineform or VectorDesigner) in which to stitch two copies of the PDF output together and rotate the result. As an example, here's the A3 PDF of the Mac OS X overlay that I made in Lineform.

BTW, what kind of printer are you using? I think some HP models have Univers built-in.

It's a Samsung. It doesn't matter, though: it even works if I simply save the EPS or PDF file and open it in Preview, without ever sending it to the printer.

That's how I took the two screenshots of the word “eject” that you can see on the webpage: I made an EPS file of it, then used pstopdf to convert it to PDF, then used image to scale by 400% and convert to PNG. Here's the EPS file in case you want to try it for yourself.
