Epson LQ-570/1070
The Epson LQ-570 and LQ-1070 dot matrix printer were introduced in August 1991 as an addition to the 24 pin range. They supported the new ESC/P2 command language which offers scalable fonts and enhanced graphics. The printers also have versatile paper handling allowing the user to select one of 4 paper paths. The printers have two sets of DIP (Dual In-line Package) switches located on the front panel. These switches control certain printer functions and default settings, the details of which are listed below.
