Don't you want to render your image at a higher resolution?  An 
Photoshop will allow you to change the ppi under
Image->ImageSize | Resolution
but all that it is doing is resizing the image to a larger resolution, 
using, I guess, some mode of interpolation.  But it really is not 
increasing the amount of information beyond what was in the original 
image.  I suspect the new resolution it chooses relates to the 133 lines 
per inch standard of commercial printing?
