[Function] Specifying the 8-dot double density bit image

[Range] 1 £ n1 + 256 ´ 2 £ 378
[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 image.
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.
