PowerPDF is a set of non-visual components with which we can create documents in PDF format.
The generated documents will be in PDF 1.2 format. Be careful, this component is for creating PDFs and not for reading them. You may think that you will never use it, but the fact is that some report generators use it, so I recommend that you install it.
