Normally, you use a sharp instrument to scrape away the lacquer so the metal shows through. Then you etch it with acid. Then you remove all the lacquer, apply ink, and print. You get ink wherever you scraped away the lacquer; it makes very fine lines.
The laser would replace the sharp instrument, cutting through the lacquer to expose the metal underneath. The rest of the steps would be the same.
