I heard the 5550 is a great printer with a low cost-per-page.
Is the 5650 the same as the 5550, only better? Does it use the same ink
cartridges?
The both use the same #56 black, #57 tricolor and #58 photo (to use the
#58, you remove the #56 and put the #58 in it's place.)
The 5650 is slightly faster and has a higher monthly duty rating (5000
pages/month vs 3000 pages/month.) It also has a larger paper tray (150 vs
100 sheets.)
