When I was designing homes I did an incredible amount of printing. The cost of the time necessary to refill cartridges, reset the chips, and review all the documents to replace pages that printed poorly due to bad ink or clogged cartridges was considerably higher than just buying generic replacement cartridges.
At the time my 48" printer used standard HP inkjet cartridges so I bought other HP printers that used the same cartridges to keep cost down.
Now, I use a Dell color laser, the generic cartridges keep my cost per page to about 5 cents. Kodak is also a great company for inexpensive printer cartridges.
