Solution 1

The printer units are used by the program that creates the printer output to format the text/images, based on the orientation and size of the selected print device and paper. The printer itself has no concept of these values.

Hi,
Thanks for your answer.
I have a software that gets the unit of set paper size in the layout tab of the printer setup dialog box in a lable(e.g. width:21.7cm). that is why i say this is possible, but i had surfed many sites and I have found no related topic.

Yes, that is the paper size, in the default units of the system locale. What else are you looking for?

How can I get its dimention? means inch, cm or mm?

Richard MacCutchan 6-Jul-19 15:47pm

You have the dimension: 21.7 cm. What exactly are you trying to get?

Member 13325846 6-Jul-19 16:28pm

I cannot to have unit (cm) i want to have the unit in a lable. 21.7 without its unit is accessible in paper size properties. do you any way to have the selected unit from printer setup dialog box?

I assume you mean PaperSize Class (System.Drawing.Printing) | Microsoft Docs[^]

No, if you Open printer Properties from Microsoft Word and go to the Layout tab, in a combobox named Unit Of Metrics, you will see what is my mean. is there a way to attach an image here for you?

I don't see that on my version of Word. But units of measurement are only related to the paper size, not the printer. You can use any unit type to print your data but it must be relative to the actual paper size that you select.

I changed the Unit Of Metrics to Centimeter, Millimeter and inch but it only gives the pagesize width & Height in One-hundred of inches, So:

C#

In FormA_Load 
{
            PageSettings pgSting = new PageSettings();
           
            lblPaperSizeReslt.Text = "Width: " + ((Math.Round((double)pgSting.PaperSize.Width, 2)) / 100).ToString() + "In" +
                " × " + "Height: " + ((Math.Round((double)pgSting.PaperSize.Height, 2)) / 100).ToString() + "In";
}

And also on a button click:

C#

private void xBtnPrntrSetup_Click(object sender, EventArgs e)
        {
            PrintDialog pd = new PrintDialog();
            pd.ShowDialog();

            lblPaperSizeReslt.Text = "Width: " + ((Math.Round((double)pd.PrinterSettings.DefaultPageSettings.PaperSize.Width,2))/100).ToString() +"In"+
                " × " + "Height: " + ((Math.Round((double)pd.PrinterSettings.DefaultPageSettings.PaperSize.Height,2))/100).ToString()+ "In";

        }

This may be simple for somebody but also may save some others time. I hope this help.
