Abstract

PURPOSE:To simplify the operations of keys caused by the correction of the document data by discontinuing a printing operation and at the same time displaying the explanation information on a help information memory when a help information display command key is operated during a printing action. CONSTITUTION:If a help information display command key is operated while the characters and the symbols are printed by a print means, a command means gives a command to the print means to discontinue its printing action and also gives a command to a help information display control means to display the explanation information stored in a help information memory. The print means receives the interruption command and discontinues its printing action, and the help information display control means receives the display command and reads the explanation information out of the help information memory to display it on a display means. Thus it is possible to easily display the explanation information on the correcting function with a simple key operation when the correction noticed in a printing operation is applied to the document data. Then the key operations can be simplified for correction jobs.
