HP 6978 stopped printing in color

[TammieSweet]

I was low on ink and the printer was printing in color at the time.  Put new cartridges in and now the printer won't print in color.  Swapped back to old color cartridges and still does not work.  Have reinstalled all software, reset to factory defaults, re-updated printer, have tried everything via the support forums but still not working.

Yes I tried everything.  The only thing HP can say is you just need to buy a new printer.  This printer has barely been used.  This seems quite unacceptable.  It was working, although the ink levels were low, it was printing color. Then I change the cartridges and all of the sudden color stops printing all together. Seems very odd.
