The point of using the freezer paper through the printer (either attached to a blank sheet or fabric) is because the pattern/motif/shape/image is ALREADY stored on your computer.
Yes, one could print it out, trace it onto the freezer paper and then cut it out. But it's way it's way easier to do it in one-step (whether I'm printing on the FP or fabric/Inklingo).
You can still cut out stacks after you print the accurate image on the first page (if you need multiple copies).
If one is doing a free-form original drawing by hand, then a printer isn't even needed.
