Indeed. I have a HP4000 with network card and duplexer. It cost me £20 ten years ago and is still on the cartridge it came with. Better (cheaper) to see if an office is disposing of its old printers, rather than going to one of the 'refurbed' suppliers. All they do is a quick test print on them, then add 90% to the price.
