 
 <prompt> How dis one dey work for practice? Given di previous question, write one context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: ```One servo system dey different from some stepper motor applications because the position feedback dey continuous while the motor dey run; a stepper system dey depend on the motor not to "miss steps" for short term accuracy, although a stepper system fit include a "home" switch or other element to provide long-term stability of control. For example, when one typical dot matrix computer printer dey start up, the controller make the print head stepper motor drive go reach im left-hand limit, where one position sensor define home position and stop stepping. As long as power dey on, one bidirectional counter for the printer's microprocessor dey keep track of print-head position.```
