Demand publishing royalty accounting system

A document printer in combination with a transaction accounting system for accounting of copies of documents having an area of electrical conductivity, said document printer comprising platen means adapted to receive a document for display thereon and document reproduction means including blank paper feeding means, document scanning means, copy reproduction means and electric power supply means operatively connected to said document reproduction means to prepare copies of said document on blank paper, document conductivity sensing means carried by said platen means to sense the electrical conductivity of an area of said document;

• and switch means in said electrical power supply means to interrupt said power supply to said printer when said sensing means detects an area of electrical conductivity on said document, said transaction accounting system comprising data processing means to record, store or communicate transaction data;
• data input means for input of data on copyright code, transaction date, user identification or number of copies;
• enabling means to restore said power supply to the document reproduction means of said printer upon completion of said input data by said data input means, said enabling means requiring input of user identification and transaction date data by said data input means, and
• output data terminal means to deliver transaction data for processing or transmission to a remote accounting system.
