Digital BW, The Print

I didn't see the question I posed in the last post, so I'll try again. Please 
excuse me if this is redundant to some of you, but the post came in blank to 
me.
Does anyone know if one must use multiple dongles when using the pro 24 piezo 
rip if printing on more than one printer?
I obviously don't know anything about dongles, so please pardon me, but if 
the Pro 24 if being advertised as useful for multiprinting, then must one 
order as many dongles as one has printers?
Thanks in advance,
