Adrian Caspersz has brought this to us :
I prefer printers built for offices. They have better ink capacity, larger
paper trays and cheaper replacement compatible carts. From companies like
printerland.co.uk they are not that much different in cost than what you may
find in John Lewis...

I have add an ex-office throwaway HP4000 laser, complete with
networking card - it was free for collection. I must have had it for a
decade now it has only needed a replacement compatible toner cartridge
and paper. It just works when needed, which is not that often. I also
have a couple of freecycle SOHO colour lasers, which are needed even
less often. For one of them I managed to get a very cheap set of new
cartridges. These work via a print server, all in the spare room, all
powered via a wireless remote control power switch - so I can turn
printers on from anywhere, print, then switch off.
