The laser doesn't print anything. I haven't taken apart a home printer but I assume it works the same as the smaller machines I fix. The laser charges the drum. That puts the image on the drum by attracting toner. Then the paper rolls over the drum. I skipped some steps but that's the general idea.

The point is the laser just has to be good to charge the drum.
