  • Stencil making and printing system, control method, and stencil making and printing machine
    Patent number: 6532868
    Abstract: A stencil making and printing machine outputs a busy signal indicative that the stencil making and printing machine is a busy state, and then, gives the busy signal as an answer to the external computer system via the controller for a predetermined time after the stencil making process and for a predetermined time after a printing process, and thereby, an intervention operation from the external computer system is limited. By doing so, the present invention provides a stencil making and printing system and a stencil making and printing machine, which can improve an operability of stencil making and printing process, and has a high processing efficiency.
