[alt-photo] printer weirdness

[Joseph Smigiel]

Our college's Photo Lab just purchased a new Epson Stylus Pro 4900 and
we are running Photoshop CS5.1 with Mac OSX v10.6.8 on an I-Mac.  I'm
trying to calibrate the color output using a new X-Rite ColorMunki.
I've run the auto calibration for that colorimeter and have profiled
the monitor and printer using that device.  I'm using the standard
Adobe Ole.tiff file to check the output.  The paper is Ilford Galerie
Smooth Pearl and I've loaded the proper icc profile for that paper
initially and set the print driver to the recommended semigloss paper
type setting before loading the profiles generated by the ColorMunki.

I must have something set wrong because the printer is printing a pale
blue surrounding the image.  The image file is only 3"x4" and the
maximum printing area around it on the letter-sized paper has this
blue tint with a paper-white margin.  This is happening with two
different computers networked to the printer.

Anyone know why the 4900 is printing something in this non-image area?

I've turned color management off in the printer dialog but have also
tried some with the printer managing color and I get the same result
with the blue surround.  I've tried having proof settings on or off,
simulating paper white on or off, and so on with no apparent
difference in the printing.

What's going on?  I'm lost.
