PDFCreator Server uses a Windows service to convert files without any user interactions. Users can print to a PDFCreator Server printer and the printed files will automatically be converted according to the PDFCreator Server settings of the queue that was assigned to the printer. There is no interaction necessary after starting a print job.
Because of this you can share your PDFCreator Server printers in your network. Users can print to them and convert files without a PDFCreator installation on their computer.
