NEe J-LPD782 rpm~[~~~~ill~W DOT MATRIX PRINTER CONTROLLER DESCRIPTION F EATU RES PIN CONFIGURATION The I'PD782 is an LSI Dot Matrix Printer Controller chip which contains all the circuitry and control functions for interfacing an 8-bit processor to the Epson Model 210,220 and 240 Dot Matrix Printers.
These printers are capable of printing up to 3,1 col umns per row with 7 x 7 dot matri x.
