The explanation was in the next sentence, but perhaps could have been
clearer...
No big black ink tank means: printing B&W is more expensive
No pigment-based black tank: B&W is less dark
No extra black nozzles for fast black: B&W printing is slower (than a
similar 4-color model from the same company)
Note that this does not apply to *all* 6 color printers:
- Epson, at least, makes some printers that use pigment-based inks for
all colors. Perhaps they print dark text?
- HP and Lexmark make (or made) printers that could be configured to do
a good job with photos *or* business graphics. They hold two cartridges:
one is a 3 color cartridge. The other is either a 3 photo color
cartridge (for good photos) or a black cartridge (for business
graphics). But swapping cartridges is a hassle and cartridges that hold
multiple colors are a very expensive way to print. By now HP or Lexmark
*may* even make a printer that can hold all three cartridges at once.
