ABSTRACT:
An printer apparatus is provided with keys which allow the easy correction of an operating mistake. When an operation mode requiring entry of a large number of commands or requiring a complicated key operation is established, the user may make an error in command entries. However, such an error can be easily corrected by operating the keys. Accordingly, the manipulation of the image-forming apparatus is easy, and the cost needed to produce copies can be reduced.
