ESC L
Select Double Density Graphics Mode
Format:
ASCII code:
ESC
L (n1) (n2) (data1) (data2) . . . (data(d))
Decimal:

Hexadecimal:

4C (n1) (n2) (data1) (data2) . . . (data(d))
Explanation:
Turns on Low-Speed Double Density Graphics Mode, printing
960 dots per 8-inch line. If d is the total number of dots
required, nl and n2 are calculated thus:
nl=d MOD 256 and n2=INT (d/256).
and are followed by d data bytes.

Explanation:
Turns on High-Speed Double Density Graphics Mode,
printing 960 dots per 8-inch line. Similar to ESC L but cannot
print two adjacent dots on the same row. If d is the total number
of dots required, nl and n2 are calculated thus.
nl=d MOD 256 and n2=INT (d/256).
and are followed by d data bytes.
