嵌入式热敏打印机

简介

微型热敏打印机采用热敏技术,无需添加墨粉或上墨,性能稳定,身材小巧,节省空间。微型热敏打印机在仪器仪表、食品检测、购物终端等场景应用广泛。生活中的ATM机、存包柜、POS、超市电子称以及外卖小哥的外卖机里都有它。 打印机采用5~9V 宽电压供电方式,电压越高,打印效果越清晰。适用宽度为58MM的热敏纸卷,打印寿命 达50 公里。它支持arduino、树莓派以及Windows 串口与驱动打印。我们可以参照指令集,利用USB串口或TTL通讯接口向热敏打印机发送相应指令,打印机便能根据指令即时打印出你需要的文字、字符,条形码,二维码甚至是黑白图片; 我们可以将它和arduino控制器或树莓派利用串口连接。当配合各种传感器使用时便能DIY电子称、血压指数测量仪、土壤元素分析仪和行车记录仪等实用的仪器设备。我们也可以制作一个属于自己的小票打印机,小票上的内容任由你自己定义,经过开发甚至还可以实现远 程打印功能;

注意事项:

嵌入式热敏打印机电压越高,打印速度越快,打印出来的单据更清晰(电压范围为5~9V,)。同时,产品正常工作电流均在 0.8~1.5A 之间波动。 瞬间电流最高可达到 2A, 若天气寒冷的地方, 电流安数要求也相应增加, 打印图形的功耗一般比较大, 如果打印小票上会涉及到图形, 建议选择适合的电源!

要用arduino进行打印汉字的话,需要建立一个C文件,不能在arduinoIDE下编译(IDE开发环境无法输入中文,使用剪贴板贴入,中文也是UTF8,打印出来是乱码)。C文件中写入相关数组数据进行调用。

USB接口的支持电脑系统如XP win7 win8,需要安装驱动才可使用。USB虚拟串口可与安卓平板连接打印。 |

电源接口

  • 热敏打印机出厂默认为TTL通信接口模式,如需配置USB接口模式,需要进行以下步骤:
    • 1.通电前按住顶端走纸键两秒,通电后放开,会打印出如图字样。
  • 走纸键

    • 2.根据字样提示按住走纸键两秒,打印配置成功字样,配置结束。
  • 配置串口模式

  • 注:若要重置为TTL通信接口模式,方法与上述一致。

使用教程

准备

  • 硬件
    • 1 x Arduino UNO控制板
    • 1 x IO 传感器扩展板 V7.1
    • 1 x 直流电源
    • 1 x 热敏打印机
    • 若干 杜邦线
  • 软件

接线图

  • 如图所示,直流电源为Arduino UNO及热敏打印机提供9V供电。同时,将热敏打印机的TTL接口与此wiki示例程序定义的软串口端口(10-RXD,11-TXD)连接;

打印字符(Arduino)

  • 打印非汉字字符可直接使用print语句,例如英文字母,数字,标点符号......
  • 打印汉字则需要采取下面方式:
    • 1.建一个hz.c的文件,文件内容为新建一个字符数组(关于如何新建.c文件:建立一个.txt文件,然后修改后缀为.c就行)。

| constchar hz[][32] 实际上是声明了一个字符串数组,每个字符串不能超过32字节(GB2312编码的汉字16个),如果你要显示的汉字特别长,请修改32这个数字;此种方法实际上是将汉字全部提出到一个数组中, 应用此类方式很容易实现国际版程序,即切换数组就可以实现不同语种的显示; 【注意】:建立这个外挂文件的目的就是为了解决使用IDE编程环境无法编辑GB2312内码汉字的问题,请勿使用IDE编程环境打开编辑此文件,这样操作会将此文件改写为UTF8内码的文件! |

|

const char hz[][32]={
"DFROBOT",           //0
"极趣科技",          //1
"嵌入式热敏打印机",  //2
"arduino开发控制",   //3
"DIY趣味",             //4
"让我们一起共创未来",     //5
"打造我们的DIY世界",    //6
};

|}

    • 编写程序

|

#include"C:\Users\Administrator\Documents\Arduino\uart_dayinji\hz.c"     //引用将之前新建的hz.c文件,引号内容为hz.c文件索引地址,需要根据hz.c实际位置作出相应修改
#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX
void setup()
{
  mySerial.begin(9600);
}
void loop()
{
  mySerial.println();
  mySerial.println();
  mySerial.println("DFROBOT");
  mySerial.println();
  mySerial.println(hz[0]);
  mySerial.println(hz[1]);
  mySerial.println(hz[2]);
  mySerial.println(hz[3]);
  mySerial.println(hz[4]);
  mySerial.println(hz[5]);
  mySerial.println(hz[6]);
  mySerial.println();
  mySerial.println();
  mySerial.println();
  delay(10000);
}

|}

  • 结果在热敏纸上显示下列字符:

打印位图

  • 参考官方通用指令集第35条“定义下传位图模式”:
    • 第一步,通过PCtoLCD2002软件给一张位图取字模。(位图尺寸应满足x<255*8,y<48*8;尺寸最好是8的倍数;取字模时配置为阴码、逐列式,顺向);
    • 第二步,新建一个“imege.h”文件,将取字模得到的十六进制数组粘贴到里面,这样便得到一个位图字模库;

0x1B,0x33,0x00,
0x0A,
0x1D,0x2F,0x30                                                                                                                              //打印位图指令

};

    • 第三步,编写程序发送指令

|

#include <SoftwareSerial.h>
#include"D:\image.h"                                                                         //引用将之前新建的image.h文件,根据实际情况修改地址
SoftwareSerial mySerial(10, 11); // RX, TX

/*--------打印条形码指令,其中包含信息为“DFR0503”---------*/
char picture_S[6]={
  0x1b, 0x40,
  0x1d, 0x2A, 0x14,0x0A                                                                     //参考通用指令集34和35,0x14和0x0A是根据位图尺寸计算得来
};
char picture_E[3]={
 0xID,0x2F,0x30
};

void setup(){
  mySerial.begin(9600);
  Serial.begin(9600);
  while(Serial.read()>= 0){}
  }
void loop(){
  mySerial.println();
  mySerial.print("---------------------------------");
  mySerial.println();

  mySerial.write(show,2237);                                                                //向打印机发送打印位图指令

  mySerial.println();
  mySerial.print("---------------------------------");
  delay(5000);
}

|}

即时输入,即时打印(一个简单的名片书写程序)

  • 程序功能1.在串口助手上输“Mike”并发送给uno后,打印机会打印出“Name:Mike”;发送“1520000****”时,会自动识别为电话号码,打印机打出“Tel:1520000****”;输入以*开头的一段话“* this is a test”时,会自动识别为标注,打印机会打出“Remarks:”
