The invention presented hereby is an apparatus and method for developing a common protocol between a data source such as a scanner and a recipient in real time. It includes means for evaluating the protocol format of a data user, which may be any apparatus requiring input data, to ascertain compatibility with a data supplier. When the system detects an incompatibility, it attempts various solutions to correct the problem. The solutions entail two-way communication between a data supplier server and a data user server, both of which form the invention. The servers include means to modify protocol formats until compatibility is reached between the data user and provider. They are integral parts of the supplier and user interconnection apparatus and perform full time monitoring and protocol adjustment functions.
