<p>PURPOSE:To prevent the useless retransmission processing by exchanging the business forms according to each output form to enable a single reception-only printer to output plural exchange telegrams of different forms and asking a host computer to acquire an exchange telegram only when a terminal is kept in a receivable state. CONSTITUTION:When a transaction telegram 30 is produced from a terminal 2 for input/output of money, etc., an exchange telegram control mechanism 14 retrieves an answered store No.12A out of a terminal control table 12 and returns an answer telegram 31 to the terminal a business store after adding the contents of the exchange telegram store information if the exchange telegrams are retained. A reception-only printer control mechanism 22 of the terminal 2 displays the exchange telegram store information at a control display part 4 and then refers to a reception-only printer control table and then to the business form type and the set information on the business form information 21B. Then the mechanism 22 refers to a printer state 21A if a business form of the same type as the exchange telegram store information is set and then sends an exchange telegram acquiring request 32 to a host computer as long as the state 21A is available. Thus the useless retransmission operation can be omitted at occurrence of a fault like a printer jam, etc.</p> |
