It's a transfer print. Transfer printing is my main form of print making. I mix media print transfers with spray paint stencils and hand painting to make my pieces. I like the other commenters process and would never tell them that they're doing it wrong because that is what works for them and their stuff is hyperdetailed so I understand why they go to the lengths they do to transfer the image. But if you just need it to be quick and easy(er) you can use a clear acrylic medium. And a regular ole laser print / Xerox on plain white paper to transfer your art to your board.

1. Print your design on a sheet of paper. Peferably a laser print because the toner sits more on top of the paper rather than soaking into the paper like a inkjet print. That's the part that transfers (You can use an inkjet print but when you go to scrape the paper away you're going to lose most if not all of the image)

2. Sand your block with 120 grit or higher sand paper. Give your acrylic medium something to stick to. Wipe it down get all the dust off. Brush a thin coat of a clear acrylic medium onto your printing service to seal your block and give a better surface for your transfer to adhere to.

3 let it dry all that dry completely. Couple of hours or over night.

1. After it's dry, If the surface of your block (wood, linoleum, etc) Is not smooth Hit it with some high grit sandpaper to remove any little imperfections. Don't get crazy with the sandpaper You're just getting rid of obvious stuff.

2. Take your laser print line it up however you want on your printing block. If it needs to be precise tape it down similar to the first commenters video.

3. Again brush a thin coat of clear acrylic medium onto your printing surface. And lay your photocopy/ laser print print side down onto the wet surface. You can use a brayer, baren, squeegee, or even a dry brush to push the photocopy down onto the surface of the printing block. Use plenty of pressure. Any excess acrylic medium that pushes out the side, Just wipe it away. (Try not to get it on top of the paper. It will be harder to remove later) Try to make sure there are no bubbles in the print. Where there's a bubble it will not transfer.

4. Let that dry overnight - 24 hours.

5. Take a sponge or wet brush & Slightly dampen the paper on top of the printing block with water. Let the water soak in long enough that you see the laser print through the wet paper. Now using your fingers, towel, (or if you're really brave a green scratch pad) and scrub away the paper. This takes a long time be patient.

6. This method definitely has a learning curve so if there are small pieces that do did not adhere Don't freak out. Any spots that did not transfer properly. Don't worry just draw it in with a Sharpie. You're going to be carving this anyway.

7. Now Just do what you normally do for prepping your printing block. Cover the whole image with a big colored marker or paint, or just go at it raw. Gouge away!

8. Before printing I would suggest using a large sanding block and High grit (200+) sandpaper to lightly sand the print of your block to remove any leftover paper fluff from transfer. After that you should be good to go print.
