  • Network printing system, host terminal and network printer
    Patent number: 9626135
    Abstract: Upon completion of print data transmission, the host terminal sends to a network printer a finish command via a print port and further a forced disconnection request command via another communication port. If the finish command is lost due to a network failure, the network printer forcibly disconnects the host terminal from the print port of the network printer in response to the forced disconnection request command, thereby allowing the other host terminals to use the network printer without waiting the elapse of the time-out period.
