this is the java code

package android.pt;
import android.util.Log;
public class Cprinter {
 public static final String LOG_TAG = Cprinter.class.getName();
 static {
 try {
 Log.i(LOG_TAG, "load cprinter lib");
 System.loadLibrary("cprinter");
 } catch (Exception e) {
 Log.e(LOG_TAG, "can not load cprinter lib");
 e.printStackTrace();
 }
 }
 public native int openPrinter();
 public native int closePrinter();
 public native int getPrinterVersion(byte[] version);
 public native int setZoonIn(int widthZoonIn, int heightZoonIn);
 public native int setAlignType(int alignType);
 public native int setLeftMargin(int n);
 public native int setRightMargin(int n);
 public native int setLineSpacingByDotPitch(int n);
 public native int setWordSpacingByDotPitch(int n);
 public native int setPrintOrientation(int printOrientation);
 public native int setBold(int n);
 public native int setUnderLine(int n);
 public native int setInverse(int n);
 public native int printLF();

I add this lines and can see the functions inside the library,

import anywheresoftware.b4a.BA;
import anywheresoftware.b4a.BA.*;
@Version(1.0f)
@ShortName("Cprinter")
@Author("Victor Medrano")

but still not working. code I posted , the java source with provide by de company that sells this terminals.

I'm still looking for help.

What is not working?

In most cases it is better to create a new class that calls the native APIs. Only this class should be exposed.

Well, now I complete the library it's working. I will post it tonight.
