A daisywheel typewriter has a pointer added to one character petal so that movement of this character petal to the print position by a code key enables the pointer to be positioned at the location of the next printed character so that a user will know this location, particularly when printing between two previously printed characters. A daisywheel 1, which has a pointer 2 on one of its character petals, is moved into engagement with a platen 3 by a pivotally mounted hammer 4 being moved by a solenoid 5. Activation of a code key by a user causes a microprocessor of the typewriter to select the character petal on the daisywheel 1 having the pointer 2 and rotate it to the print position. The microprocessor also sends a modulated current wave form to a coil of the solenoid 5.
