Abstract

There is disclosed a method of controlling a television system which can connect to a printing apparatus, and has a display unit. Display/non-display of the status information is set (S13, S14). Status information of the printing apparatus is received from the printing apparatus (S101). The control is made to display the status information on the display unit when the display of the status information is set, and not to display the status information on the display unit when the non-display of the status information is set (S102, S103).

Claims

1. A display apparatus, comprising:

a receiving unit that receives error information from a printing apparatus, wherein the error information relating to a printing material or a printing medium;

a first display unit; and

a control unit that selects a first display mode or a second display mode based on whether the printing apparatus has a second display unit,

wherein the control unit selects the first display mode if the printing apparatus has the second display unit, and selects the second display mode if the printing apparatus does not have the second display unit,

wherein the first display unit avoids displaying the error information if the error information is received from the printing apparatus while the first display mode is selected, and

wherein the first display unit displays the error information in a different manner than the second display unit if the error information is received from the printing apparatus while the second display mode is selected.

4. The display apparatus according to claim 1, wherein the error information relates to a remaining amount of the printing material.

5. The display apparatus according to claim 1, wherein the error information relates to a remaining amount of an ink.

6. The display apparatus according to claim 1, wherein the error information relates to a remaining amount of a printing medium.

7. The display apparatus according to claim 1, wherein the error information relates to a remaining amount of paper sheets.

8. The display apparatus according to claim 1, wherein the error information relates to a paper jam.

9. The display apparatus according to claim 1, wherein the control unit determines whether or not the printing apparatus has the second display unit based on device information received from the printing apparatus.

10. The display apparatus according to claim 1, wherein the control unit allows a user to change the first display mode to the second display mode if the printing apparatus has the second display unit.

11. The display apparatus according to claim 1, wherein the control unit prevents a user from changing the second display mode to the first display mode if the printing apparatus does not have the second display unit.

2. A method for a display apparatus comprising a first display unit, the method comprising:

receiving error information from a printing apparatus, wherein the error information relating to a printing material or a printing medium;

selecting a first display mode or a second display mode based on whether the printing apparatus has a second display unit, wherein the first display mode is selected if the printing apparatus has the second display unit, and the second display mode is selected if the printing apparatus does not have the second display unit;

avoiding displaying the error information on the first display unit if the error information is received from the printing apparatus while the first display mode is selected; and

displaying the error information on the first display unit in a different manner than the second display unit if the error information is received from the printing apparatus while the second display mode is selected.

12. The method according to claim 2, wherein the error information relates to a remaining amount of the printing material.

13. The method according to claim 2, wherein the error information relates to a remaining amount of an ink.

14. The method according to claim 2, wherein the error information relates to a remaining amount of a printing medium.

15. The method according to claim 2, wherein the error information relates to a remaining amount of paper sheets.

16. The method according to claim 2, wherein the error information relates to a paper jam.

17. The method according to claim 2, further comprising determining whether or not the printing apparatus has the second display unit based on device information received from the printing apparatus.

18. The method according to claim 2, further comprising allowing a user to change the first display mode to the second display mode if the printing apparatus has the second display unit.

19. The method according to claim 2, further comprising preventing a user from changing the second display mode to the first display mode if the printing apparatus does not have the second display unit.

3. A non-transitory computer-readable storage medium that stores a program for causing a computer to execute a method for a display apparatus comprising a first display unit, the method comprising:

receiving error information from a printing apparatus, wherein the error information relating to a printing material or a printing medium;

selecting a first display mode or a second display mode based on whether the printing apparatus has a second display unit, wherein the first display mode is selected if the printing apparatus has the second display unit, and the second display mode is selected if the printing apparatus does not have the second display unit;

avoiding displaying the error information on the first display unit if the error information is received from the printing apparatus while the first display mode is selected; and

displaying the error information on the first display unit in a different manner than the second display unit if the error information is received from the printing apparatus while the second display mode is selected.
