No. It is not possible for the water based inks, like those in an ink jet to print white. Only Laytex and Oil paints can do that, so you could only do it on a 5 color printing press.
There was a printer released (kodak iirc) that actually had a 'white' tank of ink for use with photo print outs. It wasn't an ink that you could use to make white text on black paper, it was used more as a highlighter/lighter shade type aspect.
