Abstract
A method of media handoff from a first device to a second device comprises transmitting a first signal from the first device indicating a medium is at a predetermined handoff point. The first device receives a second signal from the second device instructing the first device to transport the medium toward the second device. The first device transports the medium toward the second device and receives a third signal from the second device indicating acceptance of the medium by the second device.

A method of media handoff from a first device to a second device, comprising:
- transmitting a first signal from said first device indicating a medium at a predetermined handoff point;
- receiving a second signal from said second device instructing said first device to transport said medium toward said second device;
- transporting said medium toward said second device;
- receiving a third signal from said second device indicating acceptance of said medium by said second device;
- receiving a fourth signal from said second device instructing said first device to transport said medium a predetermined distance;
- and
- transporting the medium said predetermined distance.
A method of media handoff from a first device to a second device, comprising:
- receiving a first signal from said first device indicating a medium at a predetermined handoff point;
- transmitting a second signal from said second device instructing said first device to transport said medium to said second device;
- transmitting a third signal from said second device indicating acceptance of said medium by said second device;
- and
- transmitting a fourth signal from said second device instructing said first device to transport the medium a predetermined distance.
A media handoff system, comprising:
- a first media handling device comprising:
- a first media driver for transporting a medium through said first media handling device;
- and
- a first controller for controlling said first media driver;
- and
- a second media handling device comprising:
- a second media driver for receiving the medium from said first media handling device and transporting said medium through said second media handling device;
- and
- a second controller for controlling said second media driver and being adapted to communicate with said first controller;
- wherein said first controller is designed to receive signals from said second controller and to start or stop said first media driver while said medium is being transported through said second media handling device in response to said signals.
