If the information is not sent back to the computer, then how does the
computer give a visual display of the amount of ink remaining in each
cartridge? In fact, the computer is sent this information continuously as a
print is being made, because I can watch the graphs go down as a large print
is being made. Computers these days receive all kinds of information from
the printer. Even my HP printer sends my computer information on ink levels
and it does it without any visible chip on the cartridge, don't ask me how.
