There is a WinForm application (not WPF !!!), you need to print one of its controls. Used Bitmap, but the picture is poor quality, blurry. And the printed horror. The question, in fact, what did I do wrong and how to improve the quality of the picture?

private void toolStripMenuItem3_Click(object sender, EventArgs e) { PrintDialog pd = new PrintDialog(); PrintPreviewDialog ppd = new PrintPreviewDialog(); pd.Document = printDocument1; printDocument1.DocumentName = "График рабочего времени"; if (pd.ShowDialog() == DialogResult.OK) { ppd.Document = printDocument1; if (ppd.ShowDialog() == DialogResult.Abort) { printDocument1.PrinterSettings = pd.PrinterSettings; printDocument1.Print(); } } } private void printDocument1_PrintPage(object sender, PrintPageEventArgs e) { Bitmap bmp = new Bitmap(tableLayoutPanel2.Width, tableLayoutPanel2.Height + 25); dataGridView1.ClearSelection(); tableLayoutPanel2.DrawToBitmap(bmp, tableLayoutPanel2.Bounds); e.Graphics.DrawImage(bmp, tableLayoutPanel2.Location); }

Ps. Bitmap.SetResolution() and PrinterSettings.DefaultPageSettings.PrinterResolution tried not to help

  • First try to fill everything with white so that there is no transparent background. - Qwertiy ♦
  • Look here . - Alexander Petrov
  • Maybe this is due to the fact that the original bitmap is designed for a different pixel size or dpi? Even on different monitors this dpi may differ, let alone from the printer and even more so. - Sergey
