This protocol enables thisline matrix printer to closely emulate a moving-head serial matrix printer butdoes not support downloaded fonts. In addition, NLQ compresses to 17.1 CPI,not 20 CPI.v The Epson-LQ emulation does not support downloaded characters or printjustification. In addition, near letter quality (NLQ) compresses to 17.1 CPI not 20CPI.266 Infoprint 6500 User’s Manual
