I should add that the Grappler LX supports HP PCL printers as well (box says Laserjet and original Deskjet), not just Epson LQ (technically any Epson ESC/P compatible printer). Besides higher resolution printing, the serial to parallel adapter was upgraded to 57.6kbps communication, up from the 9600bps the Grappler 9-pin ran at. Orange Micro's last product in that line was the Grappler IIsp, but I have yet to find much info or acquire one. What little I can find about it is that it adds support for Canon Bubblejet printers and the unit is self powered, not needing an AC adapter.
