Hi,

   In your Delphi documentation, look up instructions for how to declare ActiveX components. Hopefully, you will be given the option to do late binding rather early binding.

   If you choose late binding, then your program can work even if the ActiveX component is not installed, although you might need to trap the error that is raised when trying to access the component (if it's not there).

   The software license is a "per user" licensing model, so you would need to purchase a copy of PDF reDirect pro for each user, although the price can drop to as low as $1 per user with volume licensing. For people that only want to use the Batch printer feature or the ActiveX component, we can look at the Server version of the program.

   Unfortunately, I do not have Delphi sample code. The DLL does require that PDF reDirect Pro be fully installed for each user. Anything else would require a customized version of the program - which can be expensive to get from me. Nonetheless, I have done that for others by request.

   I hope that helps. If you want to discuss addtional details, please contact me through my e-mail  at exp (at) exp-systems(dot)com.

   Cheers!
