After seven years of output, the HP ink jet printer had finally stopped working. Because it was never intended to be serviced by mortals, it was time to find a new one. Choosing a model can be as difficult as you want to make it because HP has an estimated six billion models. For once, I delegated the obsessiveness in culling the list of models down to three.
It doesn’t take an MBA to realize that the companies make their money on the cartridges. How much was the question.
I constructed a spreadsheet to determine which model would be most economical over its lifetime.
