Hi, Peter, I made several tests:
I tried several drivers that go with Ubuntu 10.4, accessing the printer over LAN and connected directly to my laptop. (The best for this document was "HP LaserJet 2300 Foomatic/Postscript".) The effect depends mostly on the resolution set when printing -- the effect clearly happen with 600 dpi and 1200 dpi fast-res, and with true 1200 dpi it is either absent or become too small for me to tell. I also tried HP 1020 (probably no effect) and Epson Photosmart D5300 at home where I also cannot tell if is present or not. I'm not quite sure about the methods CUPS use to convert pdf to ps. I also tried to print this pdf from Acroread on Windows computer -- the effect take place. (But not with rtf files using the same font.) My printer is this one: http://h10010.www1.hp.com/wwpc/us/en/sm/WF06a/18972-236251-236263-14638-f51-238800.html; they say it has PostScript 3 Emulation. I suppose the document and applications use the font embedded in this pdf, which is Newton (http://paratype.ru/pstore/fonts/Newton.htm).
