MePOS-Print-button-WIFI-USB with decorative LED

MePOS Connect printing

This is a sample code to integrate the MePOS print feature to your application with a touch of visual interaction, by manipulating while printing the decorative LEDs. On this example we are showing the printing action with a red colour and a completed print action with a green colour.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

• Go to Mepos.io and register as developer. There you will find the latest SDK file for your project.

Installing

Add the SDK to your project

There are two options:

1 Manual

• Download the .aar
• On your project create a new module (Import AAR Package)
• Go to project structure
• Add a app module dependencies on the library
  • On scope select compile

2 Gradle Integration

You can integrate the MePOS connect library using gradle, adding the following configuration to your build.gradle file:

repositories {
 maven { url "http://connect.mepos.io/artifactory/libs-release-local" }
}

dependencies {
 compile 'com.uniquesecure:meposconnect:1.23:@aar'
}

• Prepare you manifest.xml file (necessary for wifi-printing) and include the following line:

<uses-permission android:name="android.permission.INTERNET" />

• Create a BroadcastReceiver for the USB device.

android.hardware.usb.action.USB_DEVICE_ATTACHED
android.hardware.usb.action.USB_DEVICE_DETACHED

Running the tests

1. Create MePOS receipt.
```
public class ReceiptBuilder {

    public MePOSReceipt getShortReceipt() {
        MePOSReceipt receipt = new MePOSReceipt();
        MePOSReceiptTextLine rcpt = new MePOSReceiptTextLine();

        rcpt.setText("RECEIPT", MePOS.TEXT_STYLE_BOLD, MePOS.TEXT_SIZE_NORMAL, MePOS.TEXT_POSITION_CENTER);
        receipt.addLine(rcpt);

    return receipt;
    }
}
```
2. In order to control the UI messages and set the Cosmetic LED colors during the printing cycle, implement MePOSPrinterCallback on your printing activity and its methods.

@Override
   public void onPrinterStarted(MePOSConnectionType mePOSConnectionType, String s) {
   mePOS.setCosmeticLedCol(MePOSColorCodes.COSMETIC_RED);   
       // some message
   }
   @Override
   public void onPrinterCompleted(MePOSConnectionType mePOSConnectionType, String s) {
   mePOS.setCosmeticLedCol(MePOSColorCodes.COSMETIC_GREEN);
       // some message
   }
   @Override
   public void onPrinterError(MePOSException e) {
       // some message
   }   

Note.- You can select from seven diferent colors.

• MePOSColorCodes.COSMETIC_GREEN
• MePOSColorCodes.COSMETIC_BLUE
• MePOSColorCodes.COSMETIC_CYAN
• MePOSColorCodes.COSMETIC_RED
• MePOSColorCodes.COSMETIC_YELLOW
• MePOSColorCodes.COSMETIC_MAGENTA
• MePOSColorCodes.COSMETIC_WHITE
• MePOSColorCodes.COSMETIC_OFF

3. Creating a USB MePOS instance.
```
MePOS mePOS = new MePOS(context, MePOSConnectionType.USB);
```
4. Finally send to the printer the receipt previously created.
```
MePOSReceipt receipt = new ReceiptBuilder().getShortReceipt();
mePOS.print(receipt);
```
5. For wifi printing create a wifi instance as follows:
```
MePOS mePOS = new MePOS(context, MePOSConnectionType.WIFI);
mePOS.getConnectionManager().setConnectionIPAddress("192.168.1.64");
```

About the test

The code on this repository is an example from the SDK and for MePOS developers willing to implement it.
