how do you erase dot matrix print form paper
dot matrix
Technically, yes. A dot matrix printer has a print head with small pins on it. While printing the pins fire, striking a ribbon between the print head, the paper and a platen, causing a dot to appear on the paper. These dots make up the image on the paper.
true
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.
Because the dot matrix (impact printer) fires pins (9 pins or 24 pins) against an inked ribbon to print dots on paper.

The first Dot Matrix printers were sold in 1970. These were somewhat larger than the printers of today, with the capacity to print up to 80 columns at one time. The paper had to have holes on the sides to guide the paper through the printer.
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.
Dot matrix printers, which are "impact" printers, will do it. You can still get these--you need one to print on FedEx shipping labels and things like that.
The advantages are: * low purchase cost. * can handle multipart forms. * cheap to operate, just new ribbons. * rugged and low repair cost. The disadvantages are: * noisy. * low resolution. You can see the dots making up each character. * Not all can do colour. * Colour looks faded and streaky.
Commonly known as a "Dot Matrix" printer.
A dot-matrix or a daisy wheel printer is used to print on multi-part forms and listing paper. Such printers are known as impart printers.
