Ive got a RC car which ive taken apart in order to replace with a stronger motor. The rc car has a typical dc motor but i want to replace with a printer motor which is a 12-24v type. What would be the most appropriate way to increase voltage/current so that I can still use the same circuit to provide the signal for control. Thanks in advance

This is unlikely to be an easy task. Do you know how the present motor(s) are supplied? Is a variable speed obtained by a variable DC voltage, or variable M/S pulses, or a variable pulse PRF?
Printer motors are usually stepper motors, to get a precise movement of the print head or paper. If you want to use these, you will need a stepper motor controller (plenty on Google), but the interface between the existing R/C output and the stepper motor controller is probably where you will have the most difficulty. Don't let that put you off experimentation! Read all the documentation you can find on the R/C car and the stepper motor controllers. Also don't forget that you will need larger or more batteries, and those alone will increase the weight - perhaps substantially.
