Should have an addressable limit of 720 as well. This means that sending them 
a predithered (or prehalftone dotted) image in one bit B&W (NOT grayscale) 
would produce dots in exactly the pattern of the file. You can test this by 
sending one pixel wide B&W lines (ideally both horizontal and vertical lines) to 
the printer. At 360 you'll definately get lines, at 720, it will depend on the 
model. At 1440, you should fail to get lines, as its beyond the addressable 
limit.
