A Dynamic Trunking Protocol switch in a dot matrix printer is used to change the parameters that the printer is operating under. These might be the baud rate of the printer, or the parity for data checking, or even the font size.
A dot matrix is an impact printer. A scanner is not a printer.

A basic dot matrix has 9 pins, which produces an average print. A dot matrix with 24 pins (or more) will produce a better quality print.

A line printer and dot matrix printer differ in how they print pages. Line printers are more commonly used with computers, while dot matrix printers function similarly to a typewriter.PrintingA line printer print pages exactly as its name implies, one line at a time. Dot matrix printers use pins arranged in a matrix that physically strike an ink ribbon between the pin and the paper to print characters.SpeedLine matrix printers can print roughly 1,200 lines per minute, or generally about 20 pages per minute. Dot matrix printers print about 40-300 characters per second, or about six to seven pager per minute, at best.QualityDot matrix printers have a lower print quality than line printers. The characters' shapes on pages printed using a dot matrix printer appear as a number of dots connected together. Line printers print solid characters and can use a wide variety of font face and sizes.
For the most part Dot-Matrix Printers are obsolete due to the poor quality of the copy, although some commercial companies, and organizations may use a dot-matrix to create carbon copies.
There are two types of dot matrix printer 1. unidirectional 2. bi-directional
DTP switches are used to change certain parameters of the printer, like to size of the paper, the font, the baud rate the parity and a number of others.
A line matrix is a type of printer which is a compromise between a dot matrix printer and a line printer.
