Hi,

Can somebody point me to some documentation or sample codes on how to
send ASCII data to a UNC printer path? The data are label printer
commands in ASCII text. I tried using a FileStream object but I need to
supply it with an IntPtr handle of the printer which I don't know how to
get. In Platform SDK I can use the function "CreateFile" to get a handle
but I don't know the .NET equivalent. Any ideas or there is another way
to do this?

Any help is greatly appreciated.

Thank you very much,

Raul Vallestero

Raul,

You can import the CreateFile function from the Kernel32 libary
into your application code like this:

    [DllImport("kernel32.dll")]
    private static extern IntPtr CreateFile(
        string lpFileName,
        int dwDesiredAccess,
        int dwShareMode,
        LPSECURITY_ATTRIBUTES lpSecurityAttributes,
        int dwCreationDisposition,
        int dwFlagsAndAttributes,
        IntPtr hTemplateFile
        );

You can access the printer using the features in the System.Drawing
namespace too but that probably won't be suitable if you want to
talk directly out the LPT port.

Hope this helps.
