Explanation: 

Detailed explanation-1: -Dot matrix printers can print multiple sheets at once, printing directly onto the white front sheet, then following on to the coloured carbon copies behind. In general, dot matrix printers are more reliable than laser or inkjet machines, especially when used in dirty environments such as warehouses or car garages.

Detailed explanation-2: -Unlike laser and inkjet devices, dot matrix printers can operate in environments with extreme temperatures and dust and produce a constant stream of reliable output for a long period of time. Inkjet inks and laser toner tolerate heat and cold poorly, and dust causes these devices to jam and produce inferior output.
