Unlimited Intranet is for network installations that do not have internet access and requires the user to have PDFtk installed on the intranet server. Note, we do not support PDFtk and are only able provide limited support for intranet installation due to the offline status of intranets.
To use, install PRO2PDF on your site, and install the intranet php file that is delivered after purchase. You will the be able to use the plugin on an unlimited number of forms without an internet connection. However, signatures and images are not supported with the intranet version.
