From Dane Prairie Systems:
Win2PDF 7 creates PDF, PDF/A, XPS, TIFF, and SVG files from any Windows XP, Vista, Windows 7, or Windows 8 application (including x64 editions). Win2PDF installs as a printer, so all you need to do is print from any application to create the PDF file. Create documents from any Windows application in the following formats:
PDF--Portable Document Format;
PDF/A--Portable Document Format for Archiving (PDF/A-1b, ISO 19005-1:2005);
XPS--XML Paper Specification;
TIFF--Tagged Image File Format;
SVG--Scalable Vector Graphics.
Merge PDF documents to the beginning or end of an existing PDF file. Integrates with Outlook and Outlook Express, or other MAPI e-mail clients to automatically attach PDF files to e-mail messages. Custom Windows applications including Visual Basic applications can easily interface with Win2PDF and can control the PDF file name without user intervention. The Win2PDF Pro version has all of the features of Win2PDF, but it also includes support for password protecting PDF files with 40- or 128-bit encryption, and applying a watermark.
