Brings back memories, this was my 2nd large format printer. It's slow, painfully slow and expensive to run. I had trouble with the ink filling since it doesn't have lines to the printheads so it docks them against some valves from the ink carts and fills the heads after each print. Obsolete by todays standards. Easy to replace printheads and each cartridge contains both ink and a head.
You'll probably have trouble with finding drivers compatible with newer operating systems, but with some fiddle I remember getting it to print from a windows driver and an LPT cable, no extra software needed. I think I used a Designjet 3000cp driver or something, you can download them from HP for free. Don't try to use the included RIP computer if you have it, takes ages if you have files larger than 20-50 Mb. You'll have trouble with color correction, profiles, etc. I'd suggest to not sink any money in it since the economics with this printer is not working anymore today - even if you got it for free. But I remember the take-up was nice, photocell and all... Sorry to say but I wouldn't keep it.
