For anyone that has one of these bigger printers (or any printer)a test is easy. Create a few diagonal lines and some circular objects in Corel Draw or Adobe Illustrator and raster it out with no aliasing to two separate files, one at 360ppi and the other at 720ppi Print the two separately at highest printer resolution. If there is a significant difference between the two you know the printer is resolving more than 360ppi. Canon and HP should use 300ppi and 600ppi.
