Abstract
The present invention, which includes a USB interface for receiving recording data from an external processor by using a first logical channel of multiple logical channels thereof, a recording unit for recording an image on the basis of recording data, and the USB interface for connecting with the recording unit, transfers recording data to the recoding unit via the USB interface and causes the recording unit to record, while forbidding to receive the recording data from the external processor via the USB interface during a recording operation of the recording unit.
Claims44
A recording control apparatus comprising:
- first interface means having multiple logical channels, for receiving recording data from an external processor by using a first logical channel among the multiple logical channels;
- a recording unit for recording an image on the basis of recording data;
- second interface means for connecting with said recoding unit;
- first recording control means for transmitting recording data received via said first interface means to said recoding unit via said second interface means and causing said recording unit to record;
- and
- second recording control means for transmitting the recording data through said second interface means to said recoding unit and causing said recording unit to record, while forbidding reception of recording data from the external processor by using said first interface means during the recording operation.
3 more elements
A recording control method comprising:
- a first recording control step of transmitting recording data received via a first interface that comprises multiple logical channels and receives the recording data from an external processor using a first logical channel of the multiple logical channels, to a recoding unit and causing the recording unit to record, via a second interface for connecting with the recoding unit for recording an image on the basis of recording data;
- a second recording control step of transmitting the recording data through the second interface to the recoding unit and causing the recording unit to record, while forbidding reception of recording data from the external processor using said first interface during the recording operation of the recording unit.
A recording control apparatus comprising:
- first interface means having multiple logical channels, for receiving recording data from an external processor via a first logical channel of the multiple logical channels;
- a recording unit for recording an image on the basis of recording data;
- second interface means for connecting with said recoding unit;
- first recording control means for transmitting recording data received by said first interface means to said recoding unit via said second interface means and causing said recording unit to record, after a recording semaphore of the recording data;
- and
- second recording control means for transmitting the recording data through said second interface means to said recoding unit and causing said recording unit to record, when a recoding semaphore can be obtained.
3 more elements
A recording control method comprising:
- a first recording control step of transmitting recording data received via a first interface that comprises multiple logical channels and receives recording data from an external processor, to a recoding unit, via a second interface for connecting with the recoding unit for recording an image on the basis of recording data, when a recoding semaphore can be obtained;
- and
- a second recording control step of transmitting recording data through the second interface to the recoding unit and causing the recording unit to record, when a recoding semaphore can be obtained.
A recording control apparatus comprising:
- a first interface unit comprising multiple logical channels, adapted to receive recording data from an external processor via a first logical channel of the multiple logical channels;
- a recording unit for recording an image on the basis of recording data;
- a second interface unit adapted to connect with said recoding unit;
- and
- a control unit adapted to transmit recording data received via said first interface unit to said recoding unit via said second interface means and causing the recording unit to record;
- wherein said control unit forbids reception of recording data from the external processor using said first interface unit during the recording operation.
3 more elements
A recording control method comprising:
- a recording control step of transmitting recording data received via a first interface including multiple logical channels and receiving recording data from an external processor by using a first logical channel of the multiple logical channels, to a recoding unit via a second interface for connecting with the recoding unit for recording an image on the basis of recording data, and causing to the recording unit to record,
- wherein, in said recording control step, reception of recording data from the external processor via the first interface is forbidden during the recording operation.
A record control apparatus comprising:
- first interface means including multiple logical channels, for receiving recording data from an external processor by using a first logical channel among the multiple logical channels;
- a recording unit for recording an image on the basis of recording data;
- second interface means for connecting with said recoding unit;
- and
- control means for transmitting the recording data received by said first interface means, to said recoding unit via said second interface means and causing said recording unit to record, after a recording semaphore is obtained when the recording data received via said first interface means exists.
2 more elements
A recording control method comprising:
- a reception step of receiving recording data via a first logical channel among a plurality of logical channels of a first interface from an external processor;
- and
- a control step of transmitting the recording data to a recording unit via a second interface, in a case where the recording data received via the first logical channel exists and a recording semaphore of the recording data is obtained.
