I have been playing with a 9-bit Epson LX-300 dot-matrix printer under Debian. So far was able to: send plain text to the printer:  echo 'Los comandos para configurar > /dev/usb/lp0change the printer's behavior through ESC/POS commands: echo -en '\x1B\x2D\x01' > /dev/usb/lp0 (add underline)Add it to cups: lpadmin -p LX-300 -v serial:/dev/usb/lp0 and print through it: lpr -P LX-300 -o raw text.txtNow, I'd like to use the printer's graphics mode capability. How to send a graphics file to the printer and get it to print as graphic and not plain text?
