Okie dokie. I care about as much as the people down voting me for knowing how printers work.

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.

Yeah, I was going to ask if that's the number for functional illeteracy. I know it's shockingly high in the US but it's not the same as being illetirate.
