ABSTRACT:
When any one of keys other than a start key on an operation panel is depressed after a printing operation according to a background job starts in a ready state, a system CPU for controlling all the parts of the machine sets a condition flag indicative of the start of a front job. By virtue of the flag, the CPU determines the front job is being executed, and even if any trouble occurs in the background job, the CPU instructs a message indicator to display the trouble occurrence message for only a predetermined short period of time, and then lets the front job operation continue. The CPU controls the message indicator to display the message of the occurrence of the trouble in the background job again when the front job operation has finished.
