推荐答案

不要。

他们会看起来垃圾：屏幕分辨率是~75dpi，打印机是> 300dpi。



相反，使用PrintDocument class [ ^ ]并正确执行！

Don't.
They will look rubbish: screen resolution is ~ 75dpi, printers are >300dpi.

Instead, use a PrintDocument class[^] and do it properly!

private void btnPrint_Click(object sender, EventArgs e)
        {
            
            //PrintDocument pd = new PrintDocument();
            //pd.PrintPage += new PrintPageEventHandler(PrintImage);
            //pd.Print();      
            PrintDocument doc = new PrintDocument();
            doc.PrintPage += this.Doc_PrintPage;
            PrintDialog dlgSettings = new PrintDialog();
            dlgSettings.Document = doc;
            if (dlgSettings.ShowDialog() == DialogResult.OK)
            {
                doc.Print();
            }
        }
        private void Doc_PrintPage(object sender, PrintPageEventArgs e)
        {
            float x = e.MarginBounds.Left;
            float y = e.MarginBounds.Top;
            Bitmap bmp = new Bitmap(this.groupBoxInvoice.Width, this.groupBoxInvoice.Height);
            this.groupBoxInvoice.DrawToBitmap(bmp, new Rectangle(0, 0, this.groupBoxInvoice.Width, this.groupBoxInvoice.Height));
            e.Graphics.DrawImage((Image)bmp, x, y);
        }
