…the
main drawback of printing is that
it is often easy to remove or alter
printed marks (especially if they're
on a paper label). This means that
marks can become difficult to read
after shipping, handling, or storage, and also permits purposeful counterfeiting.…

Conclusion
Although a laser will deliver superior performance and
speed, there's no question that it's cheaper to buy a
LED than a laser. But, when the total cost of design,
