Strange drawstring problem with numbers

I have noticed that when I use drawstring to only print numbers, it just prints nothing. However if I put a letter in the string, it prints.

So, "12345" will not work, however
"a12345" will work.

Any help will be much appreciated!
Dim g As Graphics = e.Graphics
 
g.PageUnit = GraphicsUnit.Millimeter
 
g.DrawString("12345", myFont, getBrush(strColor), X, Y)

unfortunately that didn't work, and if it did, that would be crazy setting to remove!

how does changing the page unit allow me to print numbers?

can you try this code as is:

    Private Sub Form1_Paint(ByVal sender As Object, ByVal e As System.Windows.Forms.PaintEventArgs) Handles Me.Paint
        Dim myFont As Font = Me.Font
        Dim x As Integer = 10
        Dim y As Integer = 10
        Dim g As Graphics = e.Graphics

        g.PageUnit = GraphicsUnit.Display

        g.DrawString("12345", myFont, Brushes.Black, x, y)

    End Sub

If it is working like it is working for me, you may have a problem with your Font, your Brush, or your location.

I tried changing to display but the same problem.

I don't believe its a problem with the location, brush etc because I add a letter into the string and it works with the same settings.

I still don't see how changing the display unit will stop numbers from being printed? when I can print letters, special characters and line breaks.

i have used the same unit to print lines and boxes.

If I wanted to change the PageUnit permanently, it would be a big problem as its used allot.  

Anyone have any ideas why I am facing this strange problem with drawstring and numbers bearing in mind that it works fine for letters?

Hi syinner;

Dim g As Graphics = e.Graphics
Dim MyString as String
 
g.PageUnit = GraphicsUnit.Millimeter
MyString = "12345"
 
g.DrawString(MyString, myFont, getBrush(strColor), X, Y)

Found the problem...I am using PaperlessPrinter to do my testing as this is in a vmware image... it was just not printing the line

Linked up my actual printer and it printed it!!!

Any suggestions on replacing this driver...
