Communication system and communication method
A communication system includes a transmission-side processing device, and a reception-side processing device, the transmission-side processing device and the reception-side processing device communicate using a plurality of communication lines, wherein the transmission-side processing device concurrently transmits the same telegraphic messages via each of the plurality of communication lines, and the reception-side processing device is capable of concurrently receiving telegraphic messages via each of the plurality of communication lines, and when a same telegraphic message as a previously received telegraphic message is received later, invalidates the same telegraphic message received later while processing the previously received telegraphic message.
Media curl mitigation system
A printer includes: a motor driving a transport member according to an operational parameter, to transport media along a media path from a media supply to a printhead; a first distance sensor disposed on a first side of the media path to measure a first distance between the media and the first distance sensor; and a controller configured to: receive the measured distance; detect curling of the media based on the first measured distance; and responsive to detecting curling of the media, update the operational parameter at the motor.
