I want to know the answer to the following question:
List two alternatives to rotary stepper motors in printer applications.
All the background I'm provided with is that "Likewise, many computer plotters (which since the early 1990s have been replaced with large-format inkjet and laser printers) used rotary stepper motors for pen and platen movement; the typical alternatives here were either linear stepper motors or servomotors with closed-loop analog control systems.". Is that enough to answer the question?
