Well... What can I say. I'm looking at the code. First off, you may
want to spend some time with the interop and marshalling documentation.
At first glance, I think you can dispense with all of the calls to
RtlMoveMemory... You probably can do this using Marshalling attributes
and the methods of the System.Runtime.InteropServices.Marshal class -
though, I will say that this routine would probably be easier to write
in C# using unsafe code (and probably would performe better). I will
try and see if I can get time to convert this function, but right now I
can't promise anything.

Also, you should not EVER call GetLastError from VB.NET (or from VB.CLASSIC
for that matter). The return result is meaningless since the runtime
may call API functions that set that value before you call it. You should
either use Marshal.GetLastWin32Error () or the intrinsic VB.NET Err object's
LastDllError property. Both of thes methods preserve the last user called API
error codes.

Setting printer settings... System.Drawing.Printing would be the
relavent namespace to start looking at the docs..
