According to guy in the computer shop, the reason the printer stopped working is that it is NOT compatible with 64 bit Windows and all Windows are now 64 bit. The printer itself works (it's temperamental) but it's only going to work if someone happens to be running an ancient version of Windows. It is at least 15 years old, probably older. The guy in the shop said it's only any use in a museum, but I thought I'd give it a try just in case!
Can also give the cartridges separately if no-one wants the printer (one black, one cyan and two yellow BCI 6)
