2.43 GS ( k Set up and print symbol (v2.0.0)
[FORMAT] <1D>H<28>H <6B>H xL xH cn fn d1 … dk
[DESCRIPTION] xL, xH number of bytes (xL+xH x256) after xH.
cn – code number (49 – QR code)
fn – function name (or number)
k = (xL+xH x256) – 2; (-2 for cn and fn)
d1 … dk – function specific data
[FUNCTION] Handles 2-dimmensional code data and printing.

2.44 GS ( k; fn = 41H QR code; Select model (ignored) (v2.0.0)
[FORMAT] <1D>H<28>H <6B>H xL xH cn fn n1 n2
[RANGE] (xL+xH x256) = 4; (xL = 4, xH = 0)
cn – 31H
fn – 41H
n1 – ignored
n2 – ignored
[CAUTION] * Receiving of this command is supported, but not executed.
2.45 GS ( k; fn = 43H QR code; Set the size of module (v2.0.0)
[FORMAT] <1D>H<28>H <6B>H xL xH cn fn n
[RANGE] (xL+xH x256) = 3; (xL = 3, xH = 0)
cn – 31H
fn – 43H
4 ≦ n ≦ 16;
[DEFAULT] n = 4
[DESCRIPTION] Sets size of QR pixel (module) to n printer dots.
[CAUTION] * Values n = 1, 2, 3 are also valid to send, but internally n is set to 4.
