Not quite sure what you are asking about. I am not familiar with your system but get the feeling you may be trying to do something that is not actually supported by HP.
Scan drivers are normally only needed for USB installations on that particular device. If you have a printer that is network connected then you should not need any drivers to scan. You should instead use the Scan to Email and Scan to Folder features on the printer. This will allow you to create documents and store them electronically so that they can be transfered to your server for processing.
