Good printer for 8x11 paper and photos.
I wouldn't be giving this away except I needed to print on card stock which sometimes jams in this printer.
I just factory reset the printer so it's ready for you to add your Wi-Fi and favorite FAX numbers.
(To remove my HP Instant Ink credentials I had to remove the ink cartridges and Factory Reset the printer.)
