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)
