The good think is that there is a special Silver Conductive Pen and with it you can make conductive traces to design a circuit. Mainly it is used to repair pcb faults.
The bad thing is that you must route the circuit by hand and maybe you must use a transparency paper or another paper of same surface to avoid absorbe into it.
I don't know if there is a special ink for your printer to make your life easier but i think it's improbable in common inject printers to do that even if the ink exists.
