热敏打印机常用指令集
初始化打印机：Write(0x1b 0x40)
打印机实时状态：
/*
功能：返回打印机状态
参数：无
返回：
0 正常
1 线路不通
2 打印机故障
3 打印机缺纸
8 打印机纸将尽
*/

选择标准模式：Write( 0x1b, 0x53)
打印条形码：
int PrintBarCode(char *str)
{
int ret = -1;
int nlength;
unsigned char tmp[7];
memset(tmp,0x00,sizeof(tmp));
/*
* GS h n 选择条码高度

*/

tmp[1]=0x68;
tmp[2]=0x3c;
WritePort(tmp,3);
memset(tmp,0x00,sizeof(tmp));
/*
* GS H n 选择可识别字符的打印位置
* 在打印条码时选择打印可识别字符的位置
*/
tmp[0]=0x1d;
tmp[1]=0x48;
tmp[2]=0x0;
WritePort(tmp,3);
memset(tmp,0x00,sizeof(tmp));
/*
* GS w n 选择条码宽度
* 默认值n=3；n=2、3、4点宽度
*/
tmp[0]=0x1d;
tmp[1]=0x77;
tmp[2]=0x2;
WritePort(tmp,3);
memset(tmp,0x00,sizeof(tmp));
/*
* GS k m d1...dk/GS k m n d1...dn打印条码
*/
tmp[0]=0x1d;
tmp[1]=0x6b;
tmp[2]=0x49;
tmp[3]=0x12;
tmp[4]=0x7b;
tmp[5]=0x41;
WritePort(tmp,6);
nlength = strlen(str);
ret = WritePort((unsigned char *)str,strlen(str));
if(ret == nlength)
return -1;
return 0;
}
切纸：Write(0x1b,0x69) 或 Write(0x1d,0x76,0x49) 或 Write(0x1d,0x56,0x42,0x00)
