How to get HDC object of Printer

[°Ë´óɽÈË]

Since I need to call Windows API GetDeviceCaps() in C#, I must get HDC
object of printer. And I don't like to receive the PrintPage Event because I
don't
want to print the page, just to get some properties. How can I get it? Thank
you!

Jerry,

In order to get the DC of the printer, you will have to call the
CreateDC function through the P/Invoke layer. You can pass the display name
of the printer to the lpszDevice parameter.

Hope this helps.

Hi, can you tell me how to pass the parameter lpzsDriver?

[DllImport("gdi32.dll")]
static extern IntPtr CreateDC(string lpszDriver, string lpszDevice, string
lpszOutput, IntPtr lpInitData);


IntPtr dc = CreateDC("WINSPOOL", "deviceName", null, IntPtr.Zero);
