An output device adapted to operate according to data received from a host device, the output device comprising: a volatile memory for temporarily storing operating parameter values; a memory initialization processor for initializing the volatile memory in response to a specific input; a controller (201, 207) for storing operating parameter values into the volatile memory in response to a first customization command from the host device, and for controlling the output device (103; 104) based on the operating parameter values stored in the volatile memory; a first operating parameter controller for saving operating parameter data stored in the volatile memory to a nonvolatile memory in response to a second customization command from the host device, said operating parameter data comprising one or more operating parameter values; a second operating parameter controller for automatically copying said operating parameter data from the nonvolatile memory to the volatile memory after the memory initialization process; characterized in that the output device further comprises: a third operating parameter controller for storing specific information into the nonvolatile memory in response to a third customization command from the host device, said specific information being indicative of whether operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory after the memory initialization process; wherein said second operating parameter controller automatically copies said operating parameter data from the nonvolatile memory to the volatile memory after the memory initialization process when said specific information indicates operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory. a volatile memory for temporarily storing operating parameter values; a memory initialization processor for initializing the volatile memory in response to a specific input; a controller (201, 207) for storing operating parameter values into the volatile memory in response to a first customization command from the host device, and for controlling the output device (103; 104) based on the operating parameter values stored in the volatile memory; a first operating parameter controller for saving operating parameter data stored in the volatile memory to a nonvolatile memory in response to a second customization command from the host device, said operating parameter data comprising one or more operating parameter values; a second operating parameter controller for automatically copying said operating parameter data from the nonvolatile memory to the volatile memory after the memory initialization process; characterized in that the output device further comprises: a third operating parameter controller for storing specific information into the nonvolatile memory in response to a third customization command from the host device, said specific information being indicative of whether operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory after the memory initialization process; wherein said second operating parameter controller automatically copies said operating parameter data from the nonvolatile memory to the volatile memory after the memory initialization process when said specific information indicates operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory. a third operating parameter controller for storing specific information into the nonvolatile memory in response to a third customization command from the host device, said specific information being indicative of whether operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory after the memory initialization process; wherein said second operating parameter controller automatically copies said operating parameter data from the nonvolatile memory to the volatile memory after the memory initialization process when said specific information indicates operating parameter data stored in the nonvolatile memory is to be automatically copied from the nonvolatile memory to the volatile memory.
