Hi Johnny,

The Canon uses "Bubble Jet" technology which uses heat to create a 
bubble in the ink chamber which, in turn, forces a drop of ink out.  
I think the reason it has more nozzles than the Epson is that it 
doesn't use all of them all of the time due to heat build up.  I 
think I read that in Harald Johnson's book, "Mastering Digital 
Printing".
