H.P. Printer (Hoddesdon EN11)

This is an H.P. Envy printer in very good condition.. It is about 31/2 years old. All functions work perfectly but it keep losing wifi connections to my computer and keeps needing to be reset. It may be my wifi but am now replacing it anyway. If it will work on someone else's wifi it will save it going to the tip. It does have two new ink cartridges via the HP Instant Ink App. These may or may not work without the app. I don't know.
