what i use for tracing, a light table, it's basic a box with glass on top and the bottom is a lamp, i did mine, with straight lamp led and the box covers with white paper on top the glass, and them u print the image, and put your drawing paper on top printed image, than turn on light, and start to trace.
About sizes bigger than a4, u can print the image in separate a4 papers, example in case of a3, a3 is 2 sheets of a4 than using tape align and stick the two papers and then u have a3 ready to trace.
the video on previous answer using adobe photoshop i tend to use, save ink from my printer.
the problem with light box is the more thicker the paper the worse is to be visible the outlines, i use drawing paper, canson xl bristol 82 lbs works fine, hahnemuhle bristol has 120 lbs start to get hard to see but still good. anything more heavy paper u wont see much, but a fix for that is use a brighter lamp, i use 600 lumens a lamp, something more lumens with be better.
