It was working last time I used it (although some light lines appeared), has not been damaged, I just put spares or repair because sometimes these need a bit of a printer head clean or something after they have been left unused for a while.
It comes with manuals and possibly some ink and a driver mini cd-rom, but the drivers are all online as well under HP support, you can just search HP 2620 drivers.
It is an A4 printer.
