I run a website called [url removed by host] which is an online community dedicated to helping university students in Canada interested in becoming Chartered Accountants.
The site has about 250 articles in PDF format. I use Open Office Word Processor, and created these documents using the Export to PDF function. In order to increase site retention, I would like to restrict visitors from being able to print the articles. Is there any way I can do this?
You can use password protection which will enable you to restrict printing. It is trivial to remove password protection. Digital Rights Management will work, but it is expensive.
