I tried your settings, and the image appeared three times, although
compressed.  I think this is what you were seeing with grayscale files.  It
does look like it is doing color seps.  Anyway, I believe this is related to
the fact that colorbyte's "gray" profiles are not real ICC profiles.  They
follow the file format but contain only a single table of proprietary
information.  This is also why they cannot be used to softproof in Photoshop
and you have to resort to the technique outlined by Mitch.  Their color
profiles though are standard.  The profiles set on the Bitmap tab need to be
real ICC profiles.  Here's how I print grayscale with IP.  Give it a try and
see if it works for you.

My settings agree with Tom Baker's.

In my bitmap tab, I have Gray set to "Gray Gamma 2.2/Perceptual".  This
setting tells IP what source profile to assume an image is if the file isn't
already tagged.

For Embedded, I have mine set to "Apply/Perceptual".  This setting tells IP
when I load an image to honor any source profile it is tagged with.  This
could also be set to "Prompt."  In which case IP will ask you if you want to
use the file's embedded profile or the default you've set up.  I always use
the embedded one.  It seems to me that untagged images and default profiles
could lead to trouble (or at least inconsistent results.)

In Photoshop, once I've converted the image to grayscale, I always tag it
with the Gray Gamma 2.2 profile.  This usually happens automatically for me
once I convert to grayscale since my gray working space is set to Gray Gamma
2.2.

Then I load the file in IP and on the System tab, I set Printer Profile to
one of colorbyte's gray profiles which then enableds the tint picker.

Give that a shot and see if it allows you to print grayscale files.
