Sometimes you just need a quick and dirty way to convert a document into a PDF quickly and effectively.  I used to us PDFCreator a lot but have run into a few issues installing on my work laptop as well as running with Vista.  It seems that this software called Bullzip works the exact same way with the exact same result without any issues.

Download Bullzip PDF Printer From their website

Download Version 6 (local copy) bullzippdfprinter_6_0_0_702

Combine, watermark, split, and rotate your PDF’s into one file with this open source application that has a PortableApps version as well

This PDF tool allows you to merge PDF’s into one file and do some other features that are very helpful
