Thanks a lot for your answers. Setting the IPTC data as well as a manual text can tell you what kind of settings should have been used but not the actual settings being used for printing. At least in terms of test-images and paper tests it also means unnecessary work and the chances to have different printer/iptc/text settings is quite high.
I've posted a feature request to support the printersettings as footer information - if you also think that this would be a usefull feature, please support the request.
