There are some printers which do borderless only for 5x7-inch-photos and 
smaller and some do no borderless at all, but all the rest of the 
communication protocol of these printers is the same as for the 
full-borderless models. For me it seems that the driver asks the printer 
which borderless type it is (and perhaps even also the loaded paper 
size) to not make the printer with a borderless job sent when the 
printer is not capable to print it borderless. Am I correct, Dave?
