the printer died a while ago, have just found the spare cartridges 
these are only really useful if you have the right printer.  They aren't suitable for selling on - I tried a few places that either buy or donate to charity but as these are not original ones, they dont want them.  Also happy to receive advice on responsible way to dispose of them if there are no takers.
