Say NO to updates on your printer.
There are updates going around (mainly from HP) and what this does is change the firmware and makes the aftermarket chips that we use not work. So essentially they are forcing you to use their ink or toner until we have a fix for it. There has been a recent update that we know about that will affect the HP #902 and #952 cartridges, so do not update the firmware when the printer asks.
If you have any questions, call us.
