[Outline] This command prints the 8-dot double density (Half-dot print) bit image. Printing will be
unidirectional. The surplus data exceeding the printable quantity in one line will be ignored.
The printer will automatically return to the character mode after printing the bit ima ge.
The relations between the printing head pin numbers and the data are the same as the 8-dot
standard density bit image command. When printing the double density bit image, the
horizontally adjacent dots cannot be printed.
