When the set key 12 is operated (S52: Yes, S53 / S56: No, S59:
Yes), and when the item name designated by the third hierarchy pointer value 3KP is "EXIT" (S60: Yes), this control is terminated and the process returns to S10 of the setting content setting control. However, when the item name designated by the third hierarchy pointer value 3KP is other than "EXIT" (S60: No), the item content setting process (see FIG. 8) is executed (S61).
This control is started, and every time the ↓ key 14 is operated, the contents of the next item regarding the currently displayed communication protocol item are sequentially displayed (S71 to S72), and the process returns to S71. Each time the ↑ key 13 is operated, the contents of the previous item are sequentially displayed (S73 to S74), and the process returns to S71.

When the set key 12 is operated (S70: Yes, S71 and S73: No, S75:
Yes), and when the lock flag LF is not set (S76: No), the setting content of the newly set communication protocol item is stored in the predetermined storage area of the RAM 28 (S77), and the item name and the item content thereof are further stored. In addition to"*"

As described above, the lock mode capable of setting the permission mode and the prohibition mode is provided, and the second operation modes such as "Centronics" and "RS-232C" and the item names included in these second operation modes are set. When the setting mode is changed, if the prohibit mode that prohibits the change is set, these setting contents cannot be changed. Therefore, the document data and image data are received from the external device and printed. At the time of the receiving work, the setting data of the setting item is always set to the predetermined valid data without being arbitrarily changed by other operators, and the working efficiency of the receiving work can be improved.

Further, when the setting content of the item name is changed when the prohibit mode is set, a message "change prohibition" notifying that the mode is the prohibit mode is displayed on the display 10. The operator can know the reason why the setting data cannot be changed. In the laser printer P of the present embodiment, the lock mode is set by the switch panel SP, but the lock mode may be set by outputting a command to that effect from an external device.

It should be noted that, when the prohibit mode is set, the prohibited item names whose item contents cannot be changed can be arbitrarily set. It is needless to say that the present invention can be applied to various electronic devices such as personal computers capable of transmitting document data and image data to external devices. Further, the present invention can be applied to various electronic devices having a plurality of operation modes not having a hierarchical structure.
