How to use ESC/POS command 'GS v 0'
<p>please can someone explain the 'GS v 0' command? I want to print some Bitmap on my thermal printer. I can't understand the parameters xL xH yL ...</p>

<p>The following is in the programming guide, but until now I can't see solution.</p>

<p>ASCII: Gs v 0
Decimal: 29 118 48 m xL xH yL yH [d]k
Hexadecimal: 1D 76 30 m xL xH yL yH [d]k</p>

<p>0 ≤ m ≤ 3, 48 ≤ m ≤ 51
0 ≤ xL ≤ 255
0 ≤ xH ≤ 255
0 ≤ yL ≤ 255
0 ≤ d ≤ 255
k = ( xL + xH × 256) × ( yL + yH × 256) ( k ≠ 0)</p>

<p>xL, xH specifies (xL + xH × 256) bytes in horizontal direction for
the bit image.
yL, yH specifies (yL + yH × 256) dots in vertical direction for the
bit image.
[d]k specifies the bit image data (raster format).</p>
