Find the Image Size dialog. (in one of the menus)
Uncheck "resample image" and change "resolution" from 72 to 300.
Won't increase number of pixels, though.
You can however lessen the impact of the resizing by making the adjustment in lots of small increments with bicubic sampling. Won't make a huge difference, but it's often better than not.
