The linked PDF get imported improperly, it doesn't displays the "fields" ("Vorname, Nachname, Titel" etc.) at the bottom correctly (missing whitespaces). I tested this with an up to date MacBook Pro (10.7) and a Win7 64bit system.
REPRODUCIBLE with LibreOffice 3.5.3.2 (Build-ID: 235ab8a-3802056-4a8fed3-2d66ea8-e241b80), German UI, on MacOS X 10.6.8 German. There are indeed missing some whitespaces which are very important for this type of document (poor man's form, using blanks/spaces instead of form fields or dotted lines or ... like in good forms). It would be nice if we could improve this. However, IMHO a minor issue: you can easily correct it by pressing the space bar or, better, by inserting some tabs! ;-) Improved summary field a bit, lowered severity a bit.
Created attachment 72034 [details] En.wikibooks problem This PDF is generated/printed by PDFCreator / PDF Forge ( http://sourceforge.net/projects/pdfcreator/ and http://www.pdfforge.org/ ) of the web page https://en.wikibooks.org/wiki/Cascading_Style_Sheets/Print_version . It has similar problems that the whitespaces aren't handled. Very likely the same problem. Does this pdf help more?
