熱敏打印機常用指令集
初始化打印機：Write(0x1b 0x40)
打印機實時狀態：
/*
功能：返回打印機狀態
參數：無
返回：
0 正常
1 線路不通
2 打印機故障
3 打印機缺紙
8 打印機紙將盡
*/

選擇標准模式：Write( 0x1b, 0x53)
打印條形碼：

int ret = -1;
int nlength;
unsigned char tmp[7];
memset(tmp,0x00,sizeof(tmp));
/*
* GS h n 選擇條碼高度

/*
* GS H n 選擇可識別字符的打印位置
* 在打印條碼時選擇打印可識別字符的位置
*/

tmp[2]=0x0;

/*

* 默認值n=3；n=2、3、4點寬度
*/

tmp[1]=0x77;
tmp[2]=0x2;

/*

WritePort(tmp,6);
nlength = strlen(str);
ret = WritePort((unsigned char *)str,strlen(str));
if(ret == nlength)
return -1;
return 0;
}
切紙：Write(0x1b,0x69) 或 Write(0x1d,0x76,0x49) 或 Write(0x1d,0x56,0x42,0x00)
