Help and Support

Please do not email me for support or help with this plugin, use the issue tracker link above, so everyone will benefit from community questions and involvement, and I don't have to answer the same questions over and over for many individuals.

This is a Cordova plugin, firstly. You should be familiar with the Cordova plugin system before you try to use this plugin. Fortunately, it's pretty straight forward and easy to understand.

You can read more about Android plugin development for Cordova here. Knowledge of all of these internals is not necessary, but it doesn't hurt to be familiar either.

Supported interfaces (by this plugin):

Wi-Fi (Infrastructure mode)
Bluetooth (Android and iOS)
USB

BlueTooth notes:

If your app is supporting BlueTooth, you will need the following changes in you rproject:

Android permissions

    <uses-permission android:name="android.permission.BLUETOOTH" />
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

iOS

For iOS, you need to apply for an MFi PPID. Please follow the steps at https://secure6.brother.co.jp/mfi/Top.aspx
Code change in your cordova config

    <config-file parent="NSBluetoothPeripheralUsageDescription" platform="ios" target="*-Info.plist">
        <string>Bluetooth access for Brother label printer</string>
    </config-file>
    <config-file parent="NSBluetoothAlwaysUsageDescription" platform="ios" target="*-Info.plist">
        <string>Bluetooth access for Brother label printer</string>

        </array>
    </config-file>
    <config-file parent="NSLocalNetworkUsageDescription" platform="ios" target="*-Info.plist">
        <string>Used to discover printers on your network</string>
    </config-file>
    <config-file parent="NSBonjourServices" platform="ios" target="*-Info.plist">
        <array>
            <string>_printer._tcp</string>

Usage

See here for JS interfaces to the plugin: www/printer.js

There are six available methods...

findNetworkPrinters

Upon success, findNetworkPrinters will provide a list of printers that were discovered on the network (likely using WiFi). It is not considered an error for no printers to be found, and in this case the list will just be empty.

function findNetworkPrinters(success: (printers: Printer[]) => void, failure: (reason: string) => void): void

findBluetoothPrinters

Upon success, findBluetoothPrinters will provide a list of printers that were discovered that have already been paired via Bluetooth. It is not considered an error for no printers to be found, and in this case the list will just be empty.

function findBluetoothPrinters(success: (printers: Printer[]) => void, failure: (reason: string) => void): void

findPrinters

findPrinters is a convenience function that will perform the actions of both findNetworkPrinters and findBluetoothPrinters, and combine the the results into a single continuous list.

function findPrinters(success: (printers: Printer[]) => void, failure: (reason: string) => void): void

setPrinter

must be called before printViaSDK. It takes a single object that should be one of the objects returned from findNetworkPrinters, findBluetoothPrinters, or findPrinters. Upon successfully setting the printer, the success callback will be invoked. Otherwise, the error callback will be invoked with a string for an error message.

function setPrinter(printer: Printer, success: () => void, failure: (reason: string) => void): void

printViaSDK

takes one parameter, which is a base64 encoded bitmap image. The result should be a status code that is passed directly from the SDK. The status codes are documnted in the Brother SDK Appendix in section 4.2.2.5.Error Code. If everything works, the response should be "ERROR_NONE".

Clarification:

A bitmap image in this case can be any image with an encoding that is supported by the platform.

function printViaSDK(data: string, success: () => void): void

sendUSBConfig

calls the Brother SDK's printFile method. The expected input is a string containing raw print commands, which is written to a temporary file in the app cache directory, and is then sent to the printFile method and deleted afterwards. You will need a device that supports USB-OTG and a USB-OTG cable. On first run the app will request USB permissions, and it should be saved after that for subsequent prints. As-is, this method is used to send raw commands in PCL (Printer Control Language) to the printer... For example, to configure the network settings of the printer, etc... You will need to reach out to Brother for documentation of the PCL commands. You can probably find them by searching for "Brother Printer Command Reference" and appending your model number. This method could be extended easily to accept other types of file input, so you could, for example, print JPG images, etc... See here for a simple way to generate a PJL file to reconfigure the network: https://github.com/gordol/PJL-Generator

function sendUSBConfig(data: string, success: () => void): void

                    console.error(`Printing on ${this.toString(thePrinter)} returned message : ${JSON.stringify(success)}`)
                } else {
                    console.debug(`=====print via sdk ok!!!`)
                    //this.toastService.showInfo(`Badge printed successfully`)
                }


            }, (err) => {
                console.error(`Failed to print via sdk`)

        })

    }

iOS notes:

You may get errors while compiling: you need to make sure the native lib is "embed and sign" . see https://github.com/AbobosSoftware/cordova-plugin-brother-label-printer/issues/39
