Many time, print a document on pdf format is very useful. There are many program that convert document on pdf, but I prefer to use a PDFprinter.
A PDFprinter is a virtual printer that instead prints to paper, prints on a file in pdf format. A PDFprinter is very easy to use because it's like a normal printer: you click on file menu and than click on print, when you must select the printer select the PDFprinter. Another good motivation to use a PDFprinter (in my opinion the best benefit) is that you can use PDFprinter with all original formats and all programs.
In the years, I tried many PDFprinters and I chose CutePDF because is free, easy but with useful options. CutePDF works perfectly also on Windows 7, another good reason to use it. You must install only those two file (1, 2) and after few minutes you can save on PDF all files that you want. In the preference of printers (can you see from all programs), is possible set pdf quality and other normal options of a normal printer.
If you have same other PDFprinter with more options or other features write a comment and I’ll test it on Windows 7.
