[英]Printing Forms using PrintDocument
I'm trying MSDN's example of printing using PrintDocument, but it's not going so well. 我正在尝试使用PrintDocument进行MSDN打印的例子,但它并不是那么顺利。 I've got it all to compile, but when I hit print, a "Fax Sending Settings" window pops up.
我已经完成了所有编译,但是当我点击打印时,会弹出“传真发送设置”窗口。 Is this supposed to happen?
这应该发生吗? Im trying to print, not send a fax!
我想打印,而不是发传真!
What would I have to change to print this straight to the default printer instead? 我需要更改什么才能直接打印到默认打印机?
Thanks! 谢谢!

{
this.components = new System.ComponentModel.Container();
this.printButton = new System.Windows.Forms.Button();
this.ClientSize = new System.Drawing.Size(504, 381);
this.Text = "Print Example";
printButton.ImageAlign =
System.Drawing.ContentAlignment.MiddleLeft;
printButton.Location = new System.Drawing.Point(32, 110);
printButton.FlatStyle = System.Windows.Forms.FlatStyle.Flat;
printButton.TabIndex = 0;
printButton.Text = "Print the file.";
printButton.Size = new System.Drawing.Size(136, 40);
printButton.Click += new System.EventHandler(printButton_Click);
this.Controls.Add(printButton);
}
}
}
It's seems like a fax machine is your default printer, the easiest way to remedy this would be to add a print dialog before printing the page 看起来传真机似乎是您的默认打印机,解决此问题的最简单方法是在打印页面之前添加打印对话框
PrintDialog printDialog = new PrintDialog();
printDialog.Document = printDocument;
//Show Print Dialog
if (printDialog.ShowDialog() == DialogResult.OK)
{
//Print the page
printDocument.Print();
}
This will let the user select their desired printer before printing 这将让用户在打印前选择所需的打印机
Firs you should declare an object of System.Drawing.Printing.PrintDocument
: 您应该声明
System.Drawing.Printing.PrintDocument
的对象:
private System.Drawing.Printing.PrintDocument printDocument = new System.Drawing.Printing.PrintDocument();
Then add the code described in the previous answer: 然后添加上一个答案中描述的代码:
PrintDialog printDialog = new PrintDialog();
printDialog.Document = printDocument;
//Show Print Dialog
if (printDialog.ShowDialog() == DialogResult.OK)
{
//Print the page
printDocument.Print();
}
