Example
// String data
design.drawQRCode("ｱｲｳｴｵ12345",
LabelConst.CLS_ENC_CDPG_SHIFT_JIS,
LabelConst.CLS_RT_NORMAL, 10,
LabelConst.CLS_QRCODE_EC_LEVEL_H, 100, 100);
// Binary data
byte[] bindata = new byte[] {0x01, 0x02, 0x03, 0x04, 0x05};
design.drawQRCode(bindata,
LabelConst.CLS_RT_NORMAL, 10,
LabelConst.CLS_QRCODE_EC_LEVEL_H, 150, 150);
