Now that the new versions of Ghostscript are available under the free software GPL license other projects relying on Ghostscript can be fully GPL software as well. One of these projects, PDFCreator, I recently tested and I must admit I'm impressed.

PDFCreator allows you to make a PDF of anything you can print, documents, spreadsheet, presentations, anything with a print function. PDFCreator even has encryption and security features that would make it perfect for a corporate environment.
