	 Text	printed	with	a	laser	printer	will	appear	much	more	smooth	and	crisp. 	 Text	printed	on	a	9-pin	dot-matrix	printer	will	appear	as	a	bunch	of	large	dots. 	 Text	printed	with	a	24-pin	dot-matrix	printer	will	appear	more	smooth	than	a	9-pin,	with	smaller	dots	closer	together. 	 Photocopies	are	similar	in	appearance	to	laser	prints,	and	are	more	difficult	to distinguish. 	 Sometimes,	photocopies	may	have	marks,	such	as	hair	or	dirt	that	got	onto	the copying	screen.
