ESC L

Select Double Density Graphics Mode

Format:

 

ASCII

code:

ESC

L (n1) (n2) (data1) (data2) . . . (data(d))

Decimal:

2776 (n1) (n2) (data1) (data2) . . . (data(d))

Hexadecimal:

1B 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.

ESC Y

Select High Speed Double Density Graphics Mode

Format:

 

ASCII

code:

ESC

Y (n1) (n2) (data1) (data2) . . . (data(d))

Decimal:

2769 (n1) (n2) (data1) (data2) . . . (data(d))

Hexadecimal:

1B 59 (n1) (n2) (data1) (data2) . . . (data(d))

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.
