Question

我正在vb.net中编写FedEx API以使用我们的Universe数据库。到目前为止，一切都已完成，但我仍然坚持打印标签部分。 FedEx给我的代码将标签图像保存为pdf并从acrobat打印。问题是你无法真正对pdf图像做任何事情，或者至少我确定，这意味着我无法在4 x 6热敏标签上正确排列图像。我将如何做到这一点，还是有一个很好的方法来使用图像并分配x和y坐标而不会弄乱FedEx标签？这是将标签保存到打印的代码：

Sub ShowShipmentLabels(ByRef CompletedShipmentDetail As CompletedShipmentDetail, ByRef packageDetail As CompletedPackageDetail, ByVal isCodShipment As Boolean)
        If (packageDetail.Label.Parts(0).Image IsNot Nothing) Then
            ' Save outbound shipping label
            Dim FileName As String = getProperty("labelpath") + packageDetail.TrackingIds(0).TrackingNumber + ".pdf"

            SaveLabel(FileName, packageDetail.Label.Parts(0).Image)
            Mylabel.Print()

            ' Save COD Return label
            If (isCodShipment) Then
                FileName = getProperty("labelpath") + CompletedShipmentDetail.CompletedPackageDetails(0).TrackingIds(0).TrackingNumber + "CR.pdf"
                SaveLabel(FileName, CompletedShipmentDetail.CompletedPackageDetails(0).CodReturnDetail.Label.Parts(0).Image)
            End If
        End If

    End Sub
Sub SaveLabel(ByRef labelFileName As String, ByRef labelBuffer() As Byte)
        ' Save label buffer to file
        Dim LabelFile As FileStream = New FileStream(labelFileName, FileMode.Create)
        LabelFile.Write(labelBuffer, 0, labelBuffer.Length)
        LabelFile.Close()
        ' Display label in Acrobat
        DisplayLabel(labelFileName)
    End Sub

    Sub DisplayLabel(ByRef labelFileName As String)
        Dim info As System.Diagnostics.ProcessStartInfo = New System.Diagnostics.ProcessStartInfo(labelFileName)
        info.UseShellExecute = True
        info.CreateNoWindow = True
        info.WindowStyle = ProcessWindowStyle.Hidden
        info.Verb = "Print"
        System.Diagnostics.Process.Start(info)
    End Sub

如果它在屏幕上看起来很好，但在打印机上没有正确对齐，那么您应该在设备本身或驱动程序中查看打印机设置。我想和司机一起，你可能需要具体说明媒体并调整边距。

Chris，如果还没有解决，请在我们的数据库中查看此常见问题解答Shippo：http://support.goshippo.com/hc/en-us/articles/203804319-My-labels-are-not-printing-correctly-How-can-I-fix-this-

打印4x6起初可能有点令人头疼。如果它还没有为您工作，请随时评论您使用的打印机和打印机设置的详细信息。这将有助于进一步调试。

您可以选择以ZPLII格式保存图像。这样做并将其另存为ListView( children: <Widget>[ Card(child: ListTile(title: Text('One-line ListTile'))), Card( child: ListTile( leading: FlutterLogo(), title: Text('One-line with leading widget'), ), ), Card( child: ListTile( title: Text('One-line with trailing widget'), trailing: Icon(Icons.more_vert), ), ), Card( child: ListTile( leading: FlutterLogo(), title: Text('One-line with both widgets'), trailing: Icon(Icons.more_vert), ), ), Card( child: ListTile( title: Text('One-line dense ListTile'), dense: true, ), ), Card( child: ListTile( leading: FlutterLogo(size: 56.0), title: Text('Two-line ListTile'), subtitle: Text('Here is a second line'), trailing: Icon(Icons.more_vert), ), ), Card( child: ListTile( leading: FlutterLogo(size: 72.0), title: Text('Three-line ListTile'), subtitle: Text('A sufficiently long subtitle warrants three lines.'), trailing: Icon(Icons.more_vert), isThreeLine: true, ), ), Card( child: InkWell( splashColor: Colors.blue.withAlpha(30), onTap: () { print('Card tapped.'); }, child: Container( width: 300, height: 100, child: Center( child: Text( 'When tapped this Cards InkWell displays an ink splash that fills the entire card', ), ), ), )), ], )。

将Zebra打印机共享为FedexThermal。

然后在他从vb飞来执行时创建一个print.cmd脚本...

    $(function () {
        navigator.geolocation.getCurrentPosition(showPosition, positionError);
        function showPosition(position) {
            var coordinates = position.coords;
            $("#lat").val(coordinates.latitude);
            $("#lon").val(coordinates.longitude);
        }
        function positionError(position) {
            alert("oops! Error: " + position.code);
        };
    })
   
    function getDistanceFromLatLonInKm(latitude1, longitude1, latitude2, longitude2, units) {
        var p = 0.017453292519943295;    //This is  Math.PI / 180
        var c = Math.cos;
        var a = 0.5 - c((latitude2 - latitude1) * p) / 2 +
            c(latitude1 * p) * c(latitude2 * p) *
            (1 - c((longitude2 - longitude1) * p)) / 2;
        var R = 6371; //  Earth distance in km so it will return the distance in km
        var dist = 2 * R * Math.asin(Math.sqrt(a));
        document.getElementById("output").innerHTML = dist + "Km";
    }
</script>"

然后在vb中创建一个进程来运行该脚本，

为我工作。
