Convert to PDF

From commercially available PDF-related software, I collected the things mainly composed of functions to convert in cooperation with a print function of the Windows application.
There are a great many kinds, and there are a lot of things that there is not a function except making, the conversion at all, but the thing squeezing a function is very cheap and is provided.
Though even conversion should be possible, it is most suitable for thinking if I hate it by the free software.
