Ok, so correct me if I am wrong but you are asking some mechanical questions.
so, I speak in general now and if you have question ask deeper.
Force needed to drive whatever you want to drive will be exactly the same at the end part of system. But efficiency of belt system could be slightly different then efficiency of `non` pulley system (whatever it is). But again, efficiency could be neglected for sake of easy of calculation or you can put around some value that (guess) could be 80-90%.
What you will be looking is gear ratio on pulley that could alter force/speed ratio and same thing on other system.
also, you will be looking on backlash.

and the same question here: https://physics.stackexchange.com/questions/352661/
can anyone help? basically - and i really should have done this before going ahead... *sigh*... - when you have a pulley system is the amount of force on the belt less, equal, or greater, under the same *print-head* acceleration conditions, compared to a *non* pulley system?
