Hi. Well, take a screenshot with the "impr / pant" key. You open the Paint program and paste it. You copy some objects such as contact bars by selecting it where you want to leave space for the other pcb. Once modified you save it with another name. You open the other pcb and repeat a screenshot by pressing the same key. You open the previous paint file and insert it in the free position so that you can have all the objects on a single sheet. You save the modification of the paint file created and print it according to the technique you will use to obtain your pcbs.
