如何在不使用供应商SDK的情况下在android上使用热敏打印机(USB/以太网)? [英] How use thermal printer(USB/Ethernet) on android, without using vendor SDK,?

问题描述

我已经实现了EPSON SDK(用于蓝牙)并且工作正常，但是不能在其他打印机上工作，是否有任何通用方法可以实现它.什么是ESC命令，它如何工作?，

I already implemented EPSON SDK(for Bluetooth) and working fine, but not Working on other printers, is there is any general way to accomplish it. what is ESC command, How it works?,

推荐答案

请找到此一个.它将帮助您解决问题.《 ESC/POS命令参考》提供了有关ESC/POS命令的详细信息，例如标准命令语法和协议.它面向希望使用ESC/POS命令控制打印机的程序员.

Please find this one.It will help your problem. ESC/POS Command Reference provides detailed information on ESC/POS commands, such as standard command syntax and protocol. It targets programmers who want to control the printer with ESC/POS commands.

《 ESC/POS命令参考》是纸卷打印机的ESC/POS APG的替代品.因此，将不再对用于纸卷打印机的ESC/POS APG进行修订.ESC/POS命令参考包含ANK模型或日文模型等标准模型的命令信息，并且可能包含中文模型或南亚模型.其他模型(例如定制的)可能支持不同的命令或具有不同的范围，或不同的命令参数默认值.请参阅每个产品的规格.

ESC/POS Command Reference is provided as replacement of ESC/POS APG for Paper Roll Printers. The ESC/POS APG for Paper Roll Printers, therefore, will not be revised anymore. ESC/POS Command Reference contains the command information for Standard models such as ANK model or Japanese model, and may contain Chinese models or South Asia models. The other models such as customized may support different commands or have a different range, or different default value of command parameters. Please refer to each product specification for them.

使用以下代码
注意:无论蓝牙，以太网或wifi都可以使用OutPutStream对象来写打印机

Use below code
Note : you can use OutPutStream object to write printer, no matter bluetooth or ethernet or wifi

public class PrinterConstants {
public static int PORT=9100,TOTAL_CHAR=45,DIV1=10,DIV2=5,DIV3=10,DIV4=10,DIV5=10;
public static String IP="192.168.1.35";
private OutputStream printer;
public static final String UUID="00001101-0000-1000-8000-00805f9b34fb";
public PrinterConstants(OutputStream printer){
    this.printer=printer;
}

public void printString(String str) throws IOException {
    Log.i("PRINTER_PRE",str);
    printer.write(str.getBytes());
    printer.write(0xA);
    printer.flush();
}
public void storeString(String str) throws IOException {
    printer.write(str.getBytes());

    printer.flush();
}
public void printStorage() throws IOException {
    printer.write(0xA);

    printer.flush();
}
public void feed(int feed) throws IOException {
    //escInit();
    printer.write(0x1B);
    printer.write("d".getBytes());
    printer.write(feed);printer.flush();

}
public void printAndFeed(String str, int feed) throws IOException {
    //escInit();
    printer.write(str.getBytes());
    printer.write(0x1B);
    printer.write("d".getBytes());
    printer.write(feed);printer.flush();

}
public void setBold(Boolean bool) throws IOException {
    printer.write(0x1B);
    printer.write("E".getBytes());
    printer.write((int)(bool?1:0));printer.flush();
}
/**
 * Sets white on black printing
 * */
public void setInverse(Boolean bool) throws IOException {
    bool=false;
    printer.write(0x1D);
    printer.write("B".getBytes());
    printer.write( (int)(bool?1:0) );printer.flush();

}
public void resetToDefault() throws IOException {
    setInverse(false);
    setBold(false);
    setUnderline(0);
    setJustification(0);printer.flush();
}
/**
 * Sets underline and weight
 *
 * @param val
 *      0 = no underline.
 *      1 = single weight underline.
 *      2 = double weight underline.
 * */
public void setUnderline(int val) throws IOException {
    printer.write(0x1B);
    printer.write("-".getBytes());
    printer.write(val);printer.flush();
}
/**
 * Sets left, center, right justification
 *
 * @param val
 *      0 = left justify.
 *      1 = center justify.
 *      2 = right justify.
 * */

public void setJustification(int val) throws IOException {
    printer.write(0x1B);
    printer.write("a".getBytes());
    printer.write(val);
    printer.flush();
}
public void setLeftRight(String left,String right) throws IOException {
    printer.write(0x1B);
    printer.write("a".getBytes());
    printer.write(0);
    printString(left);

    printer.write(0x1B);
    printer.write("a".getBytes());
    printer.write(2);
    printString(right);

    printer.flush();
}
public void printBarcode(String code, int type, int h, int w, int font, int pos) throws IOException {

    //need to test for errors in length of code
    //also control for input type=0-6

    //GS H = HRI position
    printer.write(0x1D);
    printer.write("H".getBytes());
    printer.write(pos); //0=no print, 1=above, 2=below, 3=above & below

    //GS f = set barcode characters
    printer.write(0x1D);
    printer.write("f".getBytes());
    printer.write(font);

    //GS h = sets barcode height
    printer.write(0x1D);
    printer.write("h".getBytes());
    printer.write(h);

    //GS w = sets barcode width
    printer.write(0x1D);
    printer.write("w".getBytes());
    printer.write(w);//module = 1-6

    //GS k
    printer.write(0x1D); //GS
    printer.write("k".getBytes()); //k
    printer.write(type);//m = barcode type 0-6
    printer.write(code.length()); //length of encoded string
    printer.write(code.getBytes());//d1-dk
    printer.write(0);//print barcode

    printer.flush();
}

public void beep() throws IOException {
    printer.write(0x1B);
    printer.write("(A".getBytes());
    printer.write(4);
    printer.write(0);
    printer.write(48);
    printer.write(55);
    printer.write(3);
    printer.write(15);printer.flush();
}

public void setLineSpacing(int spacing) throws IOException {

    //function ESC 3
    printer.write(0x1B);
    printer.write("3".getBytes());
    printer.write(spacing);

}
public void cut() throws IOException {
    printer.write(0x1D);
    printer.write("V".getBytes());
    printer.write(48);
    printer.write(0);printer.flush();
}
}

使用上面的命令，您可以编写ESC/POS命令以直接输出流

by using above you can write ESC/POS commands to output stream directly
