Tractor feed has nothing to do with the type of printhead.
My old Okidata Microline 390 dot-matrix printer has a detachable tractor feed. I can use it or not, depending on the media I'm printing on.
Tractor feed and platen.
A dot matrix printer uses continuous, fan-fold paper. Such paper is fed through the printer by pegs on a roller engaging holes along both edges of the paper.
Known as a tractor feed, in which a roller with pegs that engage in holes punched along both edges of the paper, is used to move the paper through the printer. The paper used is normally continuous fan-fold listing paper. The second type of dot matrix is one that has rubber rollers instead of a tractor feed. Here, single sheets or two sheets with a carbon sheet in between, can be either hand fed or auto fed from a paper tray. A detachable tractor feed tool can be fitted if continuous listing paper is to be also used on this type of dot matrix printer.

A dot matrix is an impact printer. A scanner is not a 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.

shuttle-matrix printer is high speed printer that works like dot-matrix printer.
A line matrix is a type of printer which is a compromise between a dot matrix printer and a line printer.
That would be some old printer paper! Before ink jet and laser printers, there was the DOT MATRIX PRINTER. The holes on either side of the paper allowed it to be fed through the printer and so printing was possible. It was referred to as tractor feed paper.
Dot Matrix Printer is the cheapest printing cost.
