6x9 inches at 300ppi

When I bring up OPM, I import the image (with a black background), 
center it, and print it at 100% which yields a 6x9 at 300ppi.  
Images of varied backgrounds print very, very well with no banding.

I can try that but I do need support for 300ppi, some of my older 
images don't have enough resolution to make 12x18 prints at more 
than 300ppi.

I appreciate the help.
