Q. Explain working of DotMatrix or InkJet Printers?
Three major issues consider the quality of characters generated by DotMatrix/InkJet Printers: - Number of dots in the matrix of every character, the size of dots and addressability of the Printer. Denser matrix and smaller dots make better characters.
Addressability is the accuracy with that a dot can be produced (for example 1/120 inch means printer can put a dot with 1/120 inch of the required dot). Minimum dot matrix employed by general dot matrix printers is 9×9 dots, 18-pin and 24-pin printers use 12×24 to 24×24 matrices. Inkjets may even give up to 72×120 dots. Quality of output also relies on paper used. If ink of an Inkjet printer gets absorbed by paper, it spreads and spoils the resolution.
