如何在热敏打印机上打印图像

Question

我尝试在热敏打印件上打印图像：

   void Method()
   {
        var printDocument = new PrintDocument();
        printDocument.PrinterSettings = new PrinterSettings() { PrinterName = "zebra" };
        printDocument.PrintPage += new PrintPageEventHandler(printDocument_PrintPage);
        printDocument.Print();
    }

    void printDocument_PrintPage(object sender, PrintPageEventArgs e)
    {
        e.Graphics.DrawImage(System.Drawing.Image.FromFile(Server.MapPath("~/Images/orderedList6.png")), 0, 0);
    }

但是没有打印文件。此外，文档在打印队列中可见，我可以打印到.xps文件。

Answer 1

问题是你没有设置控制器

printDocument.PrintController = new StandardPrintController();

Answer 2

  
• 创建Flowdocument并将您的图像放入flowdocument的“BlockUIContainer”
  
• 通过循环PrintServer
查找PrintQue   
• 使用以下代码打印

IDocumentPaginatorSource flowDocument = You_Flowdocument;
var writer = PrintQueue.CreateXpsDocumentWriter(Your_printQueue);
DocumentPaginator documentPaginator = flowDocument.DocumentPaginator;
writer.Write(documentPaginator);

您可以通过热敏打印机dll使用UserPrintTicket.PageMediaSize和Desity来设置标签尺寸。
