注解

true如果是fastCopy，则打印机必须是打印概述。 如果不是，该方法 AddJob(String, String, Boolean) 将引发异常。

false如果是fastCopy，则不需要使用 XPSDrv 打印机。 要添加到队列中的 XPS 文件将转换为打印机的页面说明语言，例如 PCL 或 Postscript。 但是，此类打印调用组件对象模型（COM）。 对 COM 的调用要求调用线程具有单线程单元 （STA） 而不是多线程单元 （MTA），这是默认值。 有两种方法可以执行此作：

• 最简单的方法是在应用程序方法（通常为“”）的第一行上方添加STAThreadAttribute（即“[System.STAThreadAttribute()]）。static void Main(string[] args)。Main

• 如果需要Main线程的公寓状态MTA，则可以将调用AddJob(String, String, Boolean)放在其单元状态设置为STASetApartmentState的单独线程中。 下面的示例演示了第二种技术。

在 Windows Presentation Foundation（WPF）中打印的其他方法包括 PrintDialog.PrintDocument 该方法，该方法可用于或不打开对话框，以及 Write 许多方法和 WriteAsync 方法 XpsDocumentWriter。

public:
 System::Printing::PrintSystemJobInfo ^ AddJob();

public System.Printing.PrintSystemJobInfo AddJob();

member this.AddJob : unit -> System.Printing.PrintSystemJobInfo

Public Function AddJob () As PrintSystemJobInfo

返回

表示打印作业及其状态的一个 PrintSystemJobInfo 。

示例

以下示例演示如何用于 AddJob() 将数组发送到 Byte 打印队列。 此代码仅适用于可以检测和打印纯文本的打印机。 其中一些人不能。

// Create the printer server and print queue objects
LocalPrintServer localPrintServer = new LocalPrintServer();
PrintQueue defaultPrintQueue = LocalPrintServer.GetDefaultPrintQueue();

// Call AddJob
PrintSystemJobInfo myPrintJob = defaultPrintQueue.AddJob();

// Write a Byte buffer to the JobStream and close the stream
Stream myStream = myPrintJob.JobStream;
Byte[] myByteBuffer = UnicodeEncoding.Unicode.GetBytes("This is a test string for the print job stream.");
myStream.Write(myByteBuffer, 0, myByteBuffer.Length);
myStream.Close();

' Create the printer server and print queue objects
Dim localPrintServer As New LocalPrintServer()
Dim defaultPrintQueue As PrintQueue = LocalPrintServer.GetDefaultPrintQueue()

' Call AddJob
Dim myPrintJob As PrintSystemJobInfo = defaultPrintQueue.AddJob()

' Write a Byte buffer to the JobStream and close the stream
Dim myStream As Stream = myPrintJob.JobStream
Dim myByteBuffer() As Byte = UnicodeEncoding.Unicode.GetBytes("This is a test string for the print job stream.")

使用此方法可将设备特定的信息写入到后台处理程序文件中，Microsoft Windows 后台处理程序不会自动包含该文件。 当然，你需要知道后台处理程序文件是增强型图元文件（EMF）还是 XML 纸张规范（XPS）。 如果希望使用 Stream API，可以使用 PrintQueueStream 类而不是此方法。

AddJob调用该方法后，必须将数组JobStream写入Byte由AddJob打印作业返回或未创建打印作业的属性PrintSystemJobInfo。 此数组是打印机正常工作且未暂停时打印的内容。

在打印队列的图形用户界面（GUI）中，作业的名称为“打印系统文档”。 若要为作业指定其他名称，请使用 AddJob(String) 重载。

在 Windows Presentation Foundation（WPF）中打印的其他方法包括 PrintDialog.PrintDocument 该方法，该方法可用于或不打开对话框，以及 Write 许多方法和 WriteAsync 方法 XpsDocumentWriter。

public:
 System::Printing::PrintSystemJobInfo ^ AddJob(System::String ^ jobName);

public System.Printing.PrintSystemJobInfo AddJob(string jobName);

member this.AddJob : string -> System.Printing.PrintSystemJobInfo

Public Function AddJob (jobName As String) As PrintSystemJobInfo

参数

返回

表示打印作业及其状态的一个 PrintSystemJobInfo 。

示例

以下示例演示如何用于 AddJob(String) 将文件读取到 Byte 数组中，并将该数组发送到打印队列。 此代码假定 C： 驱动器的根目录中有一个名为 test.txt 的文件。 此代码仅适用于可以检测和打印纯文本的打印机。 其中一些人不能。

// Create the printer server and print queue objects
LocalPrintServer localPrintServer2 = new LocalPrintServer();
PrintQueue defaultPrintQueue2 = LocalPrintServer.GetDefaultPrintQueue();

// Call AddJob 
PrintSystemJobInfo anotherPrintJob = defaultPrintQueue2.AddJob("MyJob");

// Read a file into a StreamReader
StreamReader myStreamReader = new StreamReader("C:\\test.txt");

// Write a Byte buffer to the JobStream and close the stream
Stream anotherStream = anotherPrintJob.JobStream;
Byte[] anotherByteBuffer = UnicodeEncoding.Unicode.GetBytes(myStreamReader.ReadToEnd());
anotherStream.Write(anotherByteBuffer, 0, anotherByteBuffer.Length);
anotherStream.Close();

' Create the printer server and print queue objects
Dim localPrintServer2 As New LocalPrintServer()
Dim defaultPrintQueue2 As PrintQueue = LocalPrintServer.GetDefaultPrintQueue()

' Call AddJob 
Dim anotherPrintJob As PrintSystemJobInfo = defaultPrintQueue2.AddJob("MyJob")

' Read a file into a StreamReader

' Write a Byte buffer to the JobStream and close the stream
Dim anotherStream As Stream = anotherPrintJob.JobStream
Dim anotherByteBuffer() As Byte = UnicodeEncoding.Unicode.GetBytes(myStreamReader.ReadToEnd())
anotherStream.Write(anotherByteBuffer, 0, anotherByteBuffer.Length)
