zsdk

Zebra Link OS SDK Flutter plugin.

This is a flutter plugin for the Link-OS Multiplatform SDK for Zebra

Features

Feature iOS Android
Print ZPL from String ✅ ✅
Print ZPL from file ✅ ✅
Print PDF from byte array ☑️ ☑️
Print PDF from file ✅ ✅
Get printer settings ✅ ✅
Set printer settings ✅ ✅
Check printer status ✅ ✅
Print configuration label ✅ ✅
Run calibration ✅ ✅
Reboot printer ✅ ✅

Currently this plugin only supports TCP/IP connection to the Printer.

Note:

Since v3.1.0+1 the plugin supports PDF direct printing on both iOS and Android, before this version, the PDF printing was only available on Android, and it was by using some kind of workaround converting the PDF to image and printing it as image, which was not reliable and caused some issues depending on the document dimensions, etc. Now the PDF Direct printing is the right way and according to the manufacturer, you just need to be sure your printing OS is >= Link-OS v6.3 and you have installed the Virtual Device for PDF Direct.

Steps:

  1. Upgrade Zebra Printer Firmware
  2. Install and Enable Virtual Device for PDF Direct

iOS Setup

target 'Runner' do
  use_frameworks!
  use_modular_headers!

  flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end

Android Setup

No setup required

  port: 9100 //optional
).then(value) {
 final printerSettings = PrinterResponse.fromMap(value).settings;
};

Set printer settings

zsdk.setPrinterSettingsOverTCPIP(

  if(printerResponse.errorCode == ErrorCode.SUCCESS) {
    //Do something

    Status status = printerResponse.statusInfo.status;
    Cause cause = printerResponse.statusInfo.cause;
    //Do something
  }
}

Reset printer settings

zsdk.setPrinterSettingsOverTCPIP(
  address: '10.0.0.100', 
  port: 9100, //optional
  settings: PrinterSettings.defaultSettings()

   final printerResponse = PrinterResponse.fromMap(value);
   if(printerResponse.errorCode == ErrorCode.SUCCESS) {
     //Do something
   } else {
     Status status = printerResponse.statusInfo.status;
     Cause cause = printerResponse.statusInfo.cause;
     //Do something

 }

Check printer status

zsdk.checkPrinterStatusOverTCPIP(

).then(value) {
   final printerResponse = PrinterResponse.fromMap(value);
   Status status = printerResponse.statusInfo.status;
   print(status);
   if(printerResponse.errorCode == ErrorCode.SUCCESS) {
     //Do something 
   } else {
     Cause cause = printerResponse.statusInfo.cause;
     print(cause);
   }
 }

Reboot printer

zsdk.rebootPrinter(
  address: '10.0.0.100', 
  port: 9100, //optional
).then(value) {
   final printerResponse = PrinterResponse.fromMap(value);
   Status status = printerResponse.statusInfo.status;
   print(status);
   if(printerResponse.errorCode == ErrorCode.SUCCESS) {
     //Do something 
   } else {
     Cause cause = printerResponse.statusInfo.cause;
