我如何与Android明星TSP100LAN票据打印机的工作？ [英] How do I make star TSP100LAN receipt printer work with Android?
问题描述
我已经找到了一个API 这里
然而，当我运行AndroidSample测试程序我得到的错误。
当I $上的获取打印机状态按钮，我得到的打印机处于联机状态P $ PSS。此按钮看起来。
不过：</ P>
-
pressing读取从打印机数据产量失败，无法读入固件的名称。
-
pressing打印收据会导致应用程序挂起3秒。然后什么都没有。
-
pressing打印经过座收据产量不是打印成功或大挂（有时是强制关闭）。在任何情况下，没有打印。
我花了永远弄清楚如何得到它的工作。我给你什么，我可以让你开始。我是相当新的机器人，可以随意地指出的事情我做不正确。它偶尔错误地移动所述内容进行打印，从而切断顶部和底部增加了大量的空间。如果任何人都可以明白这一点我会更AP preciated。
在这里你去：
需要从APK这些文件：不要相信我修改他们无论如何： 1. RasterDocument.java 2. StarBitmap.java
主要印刷方式：
公共静态无效PrintReceipt（上下文的背景下，RelativeLayout的布局）{
字符串PORTNAME =TCP：10.1.250.20;您的打印机// IP地址
字符串portSettings =;
//必须测量布局为它正确打印，否则尺寸为零
layout.measure（View.MeasureSpec.makeMeasureSpec（layout.getLayoutParams（），宽度，View.MeasureSpec.EXACTLY）
View.MeasureSpec.makeMeasureSpec（layout.getLayoutParams（）高度，View.MeasureSpec.EXACTLY））;
layout.layout（0，0，layout.getMeasuredWidth（），layout.getMeasuredHeight（））;
点阵位图= Bitmap.createBitmap（layout.getWidth（），layout.getHeight（），Bitmap.Config.RGB_565）;
帆布油画=新的Canvas（位）;
canvas.drawColor（Color.WHITE）;
layout.draw（画布）;
INT =了maxWidth 576; //默认TSP100收到宽度
RasterDocument rasterDoc =新RasterDocument（RasterDocument.RasSpeed.Full，RasterDocument.RasPageEndMode.FeedAndFullCut，RasterDocument.RasPageEndMode.FeedAndFullCut，RasterDocument.RasTopMargin.Standard，0，0，0）;
StarBitmap starbitmap =新StarBitmap（位图，假了maxWidth）;
StarIOPort端口= NULL;
尝试
{
/ *
使用StarIOPort3.1.jar（支持USB端口）
Android操作系统版本：上2.2
* /
端口= StarIOPort.getPort（PORTNAME，portSettings，10000，背景）;
/ *
使用StarIOPort.jar
Android操作系统版本：2.1下
端口= StarIOPort.getPort（PORTNAME，portSettings，10000）;
* /
尝试
{
视频下载（500）;
}
赶上（InterruptedException异常E）{}
byte []的命令= rasterDoc.BeginDocumentCommandData（）;
port.writePort（命令，0，command.length）;
命令= starbitmap.getImageRasterDataForPrinting（）;
port.writePort（命令，0，command.length）;
命令= rasterDoc.EndDocumentCommandData（）;
port.writePort（命令，0，command.length）;
尝试
{
视频下载（1000）;
}
赶上（InterruptedException异常E）{}
}
赶上（StarIOPortException E）
{
ShowAlertMessage（背景下，失败，无法连接到打印机。+ e.getMessage（））;
}
最后
{
如果（端口！= NULL）
{
尝试 {
StarIOPort.releasePort（端口）;
}赶上（StarIOPortException E）{}
}
}
}
私有静态无效ShowAlertMessage（最终上下文的背景下，最终的字符串alertTitle，最终字符串消息）{
尝试 {
（（活动）范围内）.runOnUiThread（新的Runnable（）{
@覆盖
公共无效的run（）{
AlertDialog.Builder对话框=新AlertDialog.Builder（上下文）;
dialog.setNegativeButton（OK，NULL）;
AlertDialog警报= dialog.create（）;
alert.setTitle（alertTitle）;
alert.setMessage（消息）;
alert.show（）;
}}）;
}赶上（最终例外五）{
Log.e（PrinterFunctions.class.getName（），e.getMessage（））;
}
}
THEN： 在另一种方法，发送PrintReceipt一个RelativeLayout的。坐落在类的构造函数当前上下文。
上下文currentContext;
RelativeLayout的RelativeLayout的;
私人最终诠释receiptWidth = 576;
私人字样字体= Typeface.DEFAULT;
私人诠释normalFontSize = 23;
私人诠释largeFontSize = 28;
公共SETU preceiptClass（上下文的背景下）{
currentContext =背景;
}
公共无效SETU preceipt（字符串客户名称）{
//创建收据布局
RelativeLayout的=新RelativeLayout的（currentContext）;
RelativeLayout.LayoutParams PARAMS;
PARAMS =新RelativeLayout.LayoutParams（receiptWidth，ViewGroup.LayoutParams.MATCH_PARENT）;
relativeLayout.setLayoutParams（PARAMS）;
relativeLayout.setId（R.id.ReceiptLayout）;
//创建任何意见，你想在这里和它们添加到RelativeLayout的，使您的收据
relativeLayout.addView（whateverViewsYouCreate）;
//最后，打印收据。
新主题（新的Runnable（）{
@覆盖
公共无效的run（）{
PrintReceipt（currentContext，RelativeLayout的）;
}
}）。开始（）;
}
此外，我是新来的android的东西，这可能不是最好的方式，但它是打印。什么酷你发现我很想听到他们的声音。
I have found an API here
However, when I run the AndroidSample test app I get errors.
When I press on the "Get Printer Status" button I get "Printer is online". This button works it seems.
However:
Pressing "Read data from printer" yields "Failure. could not read in the firmware name."
Pressing "Print Receipt" cause the application to hang for 3 seconds. Then nothing.
Pressing "Print Checked Block Receipt" yields either "printing succeeded" or a big hang (sometimes force close). In any case, nothing is printed.
It took me forever to figure out how to get it to work. I'll give you what I can to get you started. I'm fairly new to android, so feel free to point out things I am be doing incorrectly. It does occasionally incorrectly print by moving the content up, thus cutting off the top and adds a lot space at the bottom. If anyone can figure that out I would be much appreciated.
Here you go:
Requires these files from the APK: Don't believe i modified them anyway: 1. RasterDocument.java 2. StarBitmap.java
Main printing method:
public static void PrintReceipt(Context context, RelativeLayout layout){
String portName = "tcp:10.1.250.20"; //ip address of your printer
String portSettings = "";
//have to measure the layout for it to print correctly, otherwise sizes are zero
layout.measure(View.MeasureSpec.makeMeasureSpec(layout.getLayoutParams().width, View.MeasureSpec.EXACTLY),
View.MeasureSpec.makeMeasureSpec(layout.getLayoutParams().height, View.MeasureSpec.EXACTLY));
layout.layout(0, 0, layout.getMeasuredWidth(), layout.getMeasuredHeight());
Bitmap bitmap = Bitmap.createBitmap(layout.getWidth(),layout.getHeight(), Bitmap.Config.RGB_565);
Canvas canvas = new Canvas(bitmap);
canvas.drawColor(Color.WHITE);
layout.draw(canvas);
int maxWidth = 576; //default width of tsp100 receipt
RasterDocument rasterDoc = new RasterDocument(RasterDocument.RasSpeed.Full, RasterDocument.RasPageEndMode.FeedAndFullCut, RasterDocument.RasPageEndMode.FeedAndFullCut, RasterDocument.RasTopMargin.Standard, 0, 0, 0);
StarBitmap starbitmap = new StarBitmap(bitmap, false, maxWidth);
StarIOPort port = null;
try
{
/*
using StarIOPort3.1.jar (support USB Port)
Android OS Version: upper 2.2
*/
port = StarIOPort.getPort(portName, portSettings, 10000, context);
/*
using StarIOPort.jar
Android OS Version: under 2.1
port = StarIOPort.getPort(portName, portSettings, 10000);
*/
try
{
Thread.sleep(500);
}
catch(InterruptedException e) {}
byte[] command = rasterDoc.BeginDocumentCommandData();
port.writePort(command, 0, command.length);
command = starbitmap.getImageRasterDataForPrinting();
port.writePort(command, 0, command.length);
command = rasterDoc.EndDocumentCommandData();
port.writePort(command, 0, command.length);
try
{
Thread.sleep(1000);
}
catch(InterruptedException e) {}
}
catch (StarIOPortException e)
{
ShowAlertMessage(context, "Failure", "Failed to connect to printer. " + e.getMessage());
}
finally
{
if(port != null)
{
try {
StarIOPort.releasePort(port);
} catch (StarIOPortException e) {}
}
}
}
private static void ShowAlertMessage(final Context context, final String alertTitle, final String message){
try {
((Activity)context).runOnUiThread(new Runnable() {
@Override
public void run() {
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setNegativeButton("Ok", null);
AlertDialog alert = dialog.create();
alert.setTitle(alertTitle);
alert.setMessage(message);
alert.show();
}});
} catch (final Exception e) {
Log.e(PrinterFunctions.class.getName(), e.getMessage());
}
}
THEN: In another method, send PrintReceipt a relativelayout. Set the current context in the constructor of the class.
Context currentContext;
RelativeLayout relativeLayout;
private final int receiptWidth = 576;
private Typeface typeFace = Typeface.DEFAULT;
private int normalFontSize = 23;
private int largeFontSize = 28;
public SetupReceiptClass(Context context){
currentContext = context;
}
public void SetupReceipt(String customerName){
//Create layout for receipt
relativeLayout = new RelativeLayout(currentContext);
RelativeLayout.LayoutParams params;
params = new RelativeLayout.LayoutParams(receiptWidth, ViewGroup.LayoutParams.MATCH_PARENT);
relativeLayout.setLayoutParams(params);
relativeLayout.setId(R.id.ReceiptLayout);
//Create whatever views you want here and add them to the RelativeLayout to make up your receipt
relativeLayout.addView(whateverViewsYouCreate);
//Finally, Print the receipt.
new Thread(new Runnable() {
@Override
public void run() {
PrintReceipt(currentContext, relativeLayout);
}
}).start();
}
Again, I'm new to the android thing, and this may not be the best way, but it is printing. Anything cool you find out I'd love to hear them.
