Oemui and Oemuni...what's the difference?

Hi,
I am currently working on trying to convert an oemuni image
printing driver to a user-mode driver instead of a kernel-mode driver
for use in Windows Vista.

First question, is there any reason an oemuni driver cannot be
implemented as a user-mode driver? I've found these two resources on
conversion
([url]http://www.unixwiz.net/techtips/win32-pdriver-ktou.html[/url] and
[url]http://msdn2.microsoft.com/en-us/library/ms801104.aspx[/url]) and
have tried converting along those guidelines, but am still unable to
compile my driver in user mode with the ddk.

Second question, is there a major difference/what is the
difference between oemuni drivers and oemui drivers? I was considering
porting the oemuni driver to oemui, since oemui is already compiled
under user mode, but I'm not sure if that's even possible.

Again, just for reference, I am working on a print driver that
saves the printed document as a sequenced image file (which has been
tested in Windows XP) and am trying to port it to a user-mode driver for
use in Windows Vista (since vista does not allow kernel-mode drivers).

Any replies/references/etc are appreciated. Thanks for taking the
time to read this thread!

P.S. I am working for a company that produces this software as a
FREERWARE utility, so I am unable to post any code due to legal
restrictions. Again, any help is appreciated.

The difference between oemui and oemuni is one is the driver UI (oemui) and
the other is the rendering add on (oemuni).
Your driver is a rendering add on, correct?

You need to use a compiler define to switch between kernel and user mode.
