PDFCreator

PDFCreator is an application for converting documents into Portable Document Format (PDF) format on Microsoft Windows operating systems. Once installed, it allows the user to select PDFCreator as their printer, allowing almost any application to print to PDF.

It is GPL-licensed free software, written in Microsoft Visual Basic, and depends on a few proprietary Windows components, such as HTML Help and Windows Printer Drivers, which practically makes it only available for Microsoft Windows environments (all 32-bit MS Windows — 95/98/NT/2000/XP and Vista). The actual PDF generation is handled by Ghostscript.
