Well, you can use them but its a lot harder for a newbie...
The electrical circuit will change, you will need a motor driver for each motor, or a dual motor driver for both...
If your doing it because of cost, then don't, it will end up costing more for the motor driver circuits alone...
And then you have to modify the code to accept a motor driver... Much harder than the servo approach...
For the printer, it needs to be laser, not inkjet.
Just laser and print onto gloss paper and your good to go
