Thermal Printer
Laser/LED printer and Inkjet printers for a couple.
-- inkjet -- laser
Such a printer is commonly known as an "Injet" printer.
I don't understand the question. "With a speed"? Inkjet printers spray ink onto paper. If you mean "with high speed", inkjets are notoriously slow, perhaps you're think of the new memjet technology. Search youtube for "memjet" and prepare to be impressed!
A dot matrix is an impact printer. Either 9 or 24 pins are fired against an inked ribbon to leave marks on the paper. An impact printer enables printing to be done on each sheet of multi-paged listing paper.
An impact printer, is one that has a mechanism that makes the letters physically strike the paper. Two examples would be a daisy-wheel and a golf-ball printer. Non-impact printers use either jets to quirt microscopic dots of ink onto the paper, or tiny electrical impulses to 'burn' the characters onto the paper. Two examples would be an ink-jet printer and a thermal printer.

A thermal printer and a laser printer are non-impact printers. A dot matrix, that fires pins against an inked roller, and uses a tractor roller to feed continuous paper through the printer, is an example of an impact printer.
