QTR-Quadtone RIP

Example : lets print a picture in the 11x19 size.
To make it easy, I take a file of the same size 11x19 but with 
different PPI, one at 600ppi and one at 200ppi.
I send both to the printer, what is it doing ? 

Will it resup/resdown the file to 360 as it is said they deal with 
360ppi files ?

Thanks
Michel
