The rendering itself isn't that large of a task and it'd all be done on the POS which has more than enough power to draw a couple circles. There's very little processing done on a thermal printer basically it's just decoding and drawing exactly what the source system tells it to. At most I'd expect it to add a second or two for the POS to do the calculations and send it to the printer.
