I have an HP 40A inkjet cartridge (black) to give away for free. I
purchased it over a year ago, prior to replacing my machine. I discovered
it in a box when I was summer cleaning and discarding.
According to the packaging, it will fit the following machines:
DeskJet 1200C
DesignJet 230
DesignJet 250C
DesignJet 330
DesignJet 350C
DesignJet 650C
CopyJet
If you want it, please let me know. Otherwise it will be discarded.
