Lazer printer and ink-jet printer?

Yes. Source: http://en.wikipedia.org/wiki/Inkjet_printer [At the bottom of the source link, the categories state "non-impact". Find is your friend, just got to know where to look.]

no,they are non-impact printers.these use a high-velocity stream of ink toward the paper.this stream is deflected generally by using an electrostatic field.
