| 摘要 | A printing device (100,101) has a first print engine (103, 303, 603, 703), a second print engine (105, 305, 605, 705), and a buffer device (107, 307, 609, 709, 711) disposed between the first (103, 303, 603, 703) and second print engines (105, 305, 605, 705). The buffer (107, 307, 609, 709, 711) is configured to store a variable amount of web substrate (106, 301, 713) received from the first print engine (103, 303, 603, 703) and feed the substrate (106, 301, 713) to the second print engine (105, 305, 605, 705). | ||

| 主权项 | 1. A printing device (100, 101), comprising: a first print engine (103, 303, 603, 703); a second print engine (105, 305, 605, 705); and a buffer device (107, 307, 609, 709, 711) disposed between said first (103, 303, 603, 703) and second print engines (105, 305, 605, 705), said buffer device having a plurality of movable rollers adjacent a plurality of fixed rollers, wherein each of said plurality of movable rollers are rotated axially through channels by electric motors each selectively activated by control circuitry in the buffer device to increase and decrease a length of substrate path; wherein said buffer device (107, 307, 609, 709, 711) is configured to store a variable amount of web substrate (106, 301, 713) received from said first print engine (103, 303, 603, 703) and feed said substrate (106, 301, 713) to said second print engine (105, 305, 605, 705). | ||
