Well, I think I figured out one reason for 'setup' cartridges.
I think these cartridges need to be used on a new printer in order to guarantee that that printer is actually used.
Otherwise some printers at some price points would be sold at a price where
the cartridges in a printer box are worth more than the sale price of the printer.
