我找到了一个API here
但是,当我运行AndroidSample测试应用时,我会收到错误。
当我按下“获取打印机状态”按钮时,我得到“打印机在线”。这个按钮看起来很有用。
但是:
按“从打印机读取数据”会产生“失败。无法读取固件名称。”
按“打印收据”会导致应用程序挂起3秒钟。没什么。
按“Print Checked Block Receipt”会产生“打印成功”或大挂(有时强制关闭)。在任何情况下,都不会打印任何内容。

我花了很长时间才弄清楚如何让它发挥作用。我会尽我所能让你开始。我对android很新,所以请随意指出我做错的事情。通过向上移动内容偶尔会错误地打印,从而切掉顶部并在底部添加很多空间。如果有人能想出来我会非常感激。
你走了:
要求APK中的这些文件:不要相信我修改了它们: 1. RasterDocument.java 2. StarBitmap.java
主要印刷方法:
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: 在另一种方法中,向PrintReceipt发送一个relativelayout。在类的构造函数中设置当前上下文。
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();
}
同样,我是android的新手,这可能不是最好的方式,但它是打印。你发现任何酷我都喜欢听他们。

阅读iOS和Android StarIO SDK的文档,我发现STAR TSP100LAN要求它处于“光栅模式”。不幸的是,iPhone和Android SDK提供的样本仅用于“行模式”打印。虽然这不是一个答案,但希望它能帮助您指明正确的方向:)
我将尝试联系Star自己,看看我是否可以直接从他们那里得到一些示例代码,祝我好运,我会在这里报告我得到的任何回复!

您是否在Activity

?并添加您的应用程序需要允许的权限?
答案 3 :(得分:0)
Star添加了一个新的Android SDK包,其功能比此主题中提到的旧版本更多(我认为是V1.0)。新的here
可用如上所述,TSP100LAN需要接收Raster命令,因为它本身就是一个图形打印机。最新的SDK包有一个更新的示例应用程序,可让您测试许多不同的打印机功能,包括一些Raster命令。
在撰写此答案时可供下载的SDK包是V2.3。手册(README_StarIO_POSPrinter_Android_SDK.pdf)声明TSP100LAN可以使用开放式现金抽屉,获取状态,打印光栅图形文本(装饰文本/将其发送到打印机)和图像文件打印(优惠券)功能。
Star还有一个编程手册,其中包含详细说明其他功能的光栅命令。见section 3.4
