Creating PDF without Adobe tools
Myth
Create PDF files without Adobe is illegal.
There are royalties to pay when creating PDF.
Reality
FALSE.
Explanations
PDF is an open format. This means that Adobe allows everyone to create software for reading and creating PDF files. (By the way Adobe distributes for free on its website describing the PDF format so that everyone can create programs capable of using the PDF format. They do this to encourage the use of PDF, which is beneficial to Adobe.)
Creating PDF files without the tools Adobe is legal.
How Adobe is it then to save money?
It's simple: By selling powerful software specializing in archiving, indexing and automated production of PDF files. This software is mainly sold to businesses.
But you, or company, you can safely create PDF files with free tools as non-Adobe PDF Creator, or PDF995 Ghostscript / GSview.
Moreover, even if you create PDFs without Adobe tools, there is no royalty payable to Adobe, whatever the amount of PDF that you produce or how you distribute. You even have the right to sell PDF files without paying anything at Adobe.
