Abstract
A settable margin control switch is actuated when a movable carriage printer approaches the right hand margin. In the keyboard operating mode, an audible alarm is sounded and a predetermined number of character positions later, the printing of keyboard originated data is blocked. In the automatic printing mode, no alarm is sounded, however, printing is terminated and a special character is printed beyond the right hand margin to indicate that the input data has overflowed the printed record.
