I try to use the PHP script "web2printer" (http://www.printer-friendly.com/) which offer three functions for a Web page: printer-friendly, convert to pdf and recommendation.

But I obtain many "Fatal error: Call to undefined function: filter_var()".
I don't know well php!
Could you help me to install and run this script?

We can get this script at http://www.pda-systems.com/downloads...-category.html

And we can get a "manual" at http://www.printer-friendly.com/2008...-webpages.html
But it's a very small manual with basic informations.

Thanks for you help
