A high-speed, impact printer capable of printing an entire line at one time. Its speed is measured in line per minute (lpm). A fast line printer can print as many as 2,000lpm. Line printers are designed to deliver higher reliability, faster throughput, and greater resistance to rough handling and hazardous environmental conditions.
This type of printers can print graphics. In order for any line printer to print graphics it must come with a graphic software integrated into the printer. In some of these line printers you must add more memory for the software. The software could come as an option, or as mention early, integrated.
Also, in some line printers, in order to print graphics, would require to install a board into the printer.
Line printers use hammer bank or print-shuttle instead of printhead. The print-shuttle has hammers instead of print wires, and these hammers are arranged in a horizontal row instead in vertical columns.
The hammers are hold in a resting position by a permanent magnetic field. To print a dot, an electrical current is applied to the hammer coil, creating an electromagnetic field opposite to the permanent magnetic field. While this printing process perform its function, the print-shuttle vibrates in horizontal direction with high speed, and the paper advance one step.
