I installed PDFCreator on Windows XP Home, SP2. Printing the test page works fine. But trying to use PDFCreator from an other application does not work. When I open the Windows printer queue of PDFCreator I see the documents there. It is as if the printer is not switched on.
This problem seemed to be solved by switching off the spooling option in Windows for PDFCreator. But now I get and error page of PDFSpooler, the error text is "Ungültiges Bild" (invalid picture).
