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

final zsdk = ZSDK();

Start the printer calibration

zsdk.doManualCalibrationOverTCPIP(
  address: '10.0.0.100', 
  port: 9100 //optional
)

Get printer settings

zsdk.getPrinterSettingsOverTCPIP(
  address: '10.0.0.100', 
  port: 9100 //optional
).then(value) {
 final printerSettings = PrinterResponse.fromMap(value).settings;
};

Set printer settings

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

).then(value) {
  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
  }
}

Reset printer settings

zsdk.setPrinterSettingsOverTCPIP(
  address: '10.0.0.100', 
  port: 9100, //optional

 }

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;
     print(cause);

   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);
   }
 }
