Abstract

A communication apparatus includes a communication unit configured to communicate with a control apparatus, which has a recording unit and executes processing in accordance with a command written to the recording unit, an accepting unit configured to accept selection of a command by a user, and a writing unit configured to write the selected command to the recording unit, and the communication apparatus comprises: a sensing unit configured to sense connection to the control apparatus via the communication unit; a determination unit configured to determine whether the recording unit has been set to a write inhibit state if the connection has been sensed by the sensing unit; and a notification unit configured to notify the user of the fact that the recording unit has been set to the write inhibit state, if the determination unit determines that the recording unit has been set to the write inhibit state.

First claim

What is claimed is:

1. A control apparatus capable of being connected to a predetermined recording apparatus, which has a recording medium configured to record a control file and executes processing in accordance with a command that is written to the control file, the control apparatus comprising:
a display control unit configured to display, on a display unit, a control menu for accepting a control instruction to the predetermined recording apparatus by a user operation;
a writing control unit configured to control to write a command corresponding to the control instruction accepted using the control menu to the control file in the recording medium; and
a first determination unit configured to determine whether or not a data-writing inhibit state is set by a hardware switch of the recording apparatus after detecting connection to the predetermined recording apparatus and recognizing the predetermined recording apparatus, wherein the data-writing inhibit state is a state for inhibiting data from being written to the recording medium,
wherein if it is determined by the first determination unit that the data-writing inhibit state is set, the display control unit controls the display unit so as to make a user recognize that the user cannot control the predetermined recording apparatus using the control menu.

2. The apparatus according to claim 1 , wherein if it is determined by the first determination unit that the data-writing inhibit state is set, the display control unit controls not to display the control menu.

3. The apparatus according to claim 1 , wherein if it is determined by the first determination unit that the data-writing inhibit state is set, the display control unit controls to display the control menu in a manner that a selection on the control menu is impossible.

4. The apparatus according to claim 3 , wherein if it is determined by the first determination unit that the data-writing inhibit state is set, the display control unit causes the control menu displayed on the display unit to be grayed out.

5. The apparatus according to claim 4 , further comprising a second determination unit configured to determine whether or not an apparatus connected to the control apparatus is the predetermined recording apparatus,
wherein if it is determined by the second determination unit that the apparatus connected to the control apparatus is not the predetermined recording apparatus, the display control unit controls not to display the control menu regardless of whether or not the data-writing inhibit state is set.

6. The apparatus according to claim 1 , further comprising a second determination unit configured to determine whether or not an apparatus connected to the control apparatus is the predetermined recording apparatus,
wherein if it is determined by the second determination unit that the apparatus connected to the control apparatus is not the predetermined recording apparatus, the display control unit controls not to display the control menu regardless of whether or not the data-writing inhibit state is set.

7. The apparatus according to claim 1 , wherein the writing control unit controls to read the control file to obtain a result of processing corresponding to the command written to the control file.

8. The apparatus according to claim 1 , wherein the command and a result of processing corresponding to the command are written to a single control file.

9. The apparatus according to claim 1 , wherein the control file has a flag area, and
when the control instruction is accepted using the control menu, the writing control unit controls to change a state of a flag in the flag area.

10. The apparatus according to claim 9 , wherein the command and the state of the flag are written to a single control file.

11. The apparatus according to claim 1 , wherein if it is determined by the first determination unit that the data-writing inhibit state is set, the display control unit displays a notification on the display unit, the notification notifying that the data-writing inhibit state is set.

12. The apparatus according to claim 1 , wherein the control apparatus is a mobile device.

13. The apparatus according to claim 1 , wherein the processing is printing processing.

14. The apparatus according to claim 1 , wherein the control apparatus connects to the predetermined recording apparatus via a wired connection.

15. A method of controlling a control apparatus capable of being connected to a predetermined recording apparatus, which has a recording medium configured to record a control file and executes processing in accordance with a command that is written to the control file, the method comprising:
displaying, on a display unit, a control menu for accepting a control instruction to the predetermined recording apparatus by a user operation;
controlling to write a command corresponding to the control instruction accepted using the control menu to the control file in the recording medium; and
determining whether or not a data-writing inhibit state is set by a hardware switch of the recording apparatus after detecting connection to the predetermined recording apparatus and recognizing the predetermined recording apparatus, wherein the data-writing inhibit state is a state for inhibiting data from being written to the recording medium,
wherein if it is determined that the data-writing inhibit state is set, the displaying controls the display unit so as to make a user recognize that the user cannot control the predetermined recording apparatus using the control menu.

16. A non-transitory computer-readable storage medium on which has been recorded a program for causing a computer to execute a method of controlling a control apparatus capable of being connected to a predetermined recording apparatus, which has a recording medium configured to record a control file and executes processing in accordance with a command that is written to the control file, the method comprising:
displaying, on a display unit, a control menu for accepting a control instruction to the predetermined recording apparatus by a user operation;
controlling to write a command corresponding to the control instruction accepted using the control menu to the control file in the recording medium; and
determining whether or not a data-writing inhibit state is set by a hardware switch of the recording apparatus after detecting connection to the predetermined recording apparatus and recognizing the predetermined recording apparatus, wherein the data-writing inhibit state is a state for inhibiting data from being written to the recording medium,
wherein if it is determined that the data-writing inhibit state is set, the displaying controls the display unit so as to make a user recognize that the user cannot control the predetermined recording apparatus using the control menu.

17. A control apparatus capable of being connected to a predetermined recording apparatus, which has a recording medium configured to record a control file and executes processing in accordance with a command that is written to the control file, the control apparatus comprising:
a detecting unit configured to detect that the predetermined recording apparatus is connected to the control apparatus;
a display control unit configured to display, on a display unit, a control menu for accepting a control instruction to the predetermined recording apparatus by a user operation;
a writing control unit configured to control to write a command corresponding to the control instruction accepted using the control menu to the control file in the recording medi
