HP5546 printer. This printer was working well when last used (only replaced as I needed a sheet feeder) and it powers on fine but I am unable to test the printing before passing on as I used HP Instant Ink Cartridges and they no longer work if the printer is unsubcribed from Instant Ink. My suggestion would be to take out a cheap instant ink subscription say 50 pages which I believe is under £5 to test it can then be cancelled if needed, Have found a code for a months free trial which should work so will give it to person that collects. Wireless or Usb. But needs Wifi for Instant Ink Subscription.
