HP Envy 4520 intermittently won’t AirPrint

[Aprintinggal]

I’ve had this printer for a couple of years without issue.  With the last software update (today) the AirPrint is only working intermittently.  Everything has been reset based on other comments (I ensured IPP enabled and AirPrint and bonjour were configured properly).  But still, sometimes my IPad/phone detect the HP Envy and sometimes it doesn’t detect any air printer.

This was never an issue for me before as I see some of the comments show this occurred for them since day 1.  I’d never had the problem before today (just in time for the school year to start - lucky me!)

Any other ideas and/or is this a new issue for other customers after this last firmware update August 2020?

@Aprintinggal, Welcome to the HP Support Community!

Let's try the below steps to see if that helps - 

  

1.) Remove All Barriers: Certain building materials can get in the way of weaker signals like Bluetooth. Metal, bulletproof glass, concrete, and plaster are particularly bad, and marble, plaster and brick aren’t great easy. So if you’re really struggling with interference, your first step should be to move your Bluetooth devices away from these materials. That means no brick walls between you and your devices, and definitely no metal desks! 

  

2.) Change Router Channel: If you have an Apple router and you’re constantly getting interference with your WiFi, try rebooting it. Upon restart, the station will search for a new channel. Specifically, a different channel than the one your Bluetooth devices is using to communicate. If you don’t have an Apple router, you may need to instead go into your router settings and try changing the channel manually. Experiment with different channels to see which one works best. 

  

3.) Move Closer to Your Router: If you often find that you’re getting interference when talking on a wireless headset while on a WiFi call (you’ll know because you’ll hear static), try moving closer to your router. This will give you a more robust WiFi connection, so the Bluetooth frequency can’t overpower it. 

  

4.) Get Away From Microwaves and Fluorescent Lighting: Both emit frequencies of 2.4GHz, and moving away from them will distance you from the source. 

Restart the wireless router, the printer, and the MAC

Perform a ping test to check the connectivity 

1. Obtain the IP address of the printer by clicking on the Wireless icon on the printer
2. On the MAC Go to Spotlight > search for Network utility > select Ping tab > enter the IP address of the printer in the box
3. Check the second box that says Send only > 10 pings
4. Click on ping > Check the results at the end if any packets are lost
5. Note: There should be 0% packet loss, share the results in your next post.

Update the printer firmware

Go to Setup > Tools > Update the printer

Click here to know different methods of updating printer firmware.

Also, check for any software updates on MAC

Click the Apple icon > About This Mac > Software Update and install any available update.

Hope this helps! Keep me posted.

HP Support have provided the stock reply to this problem, by all means give it a try, but I haven’t seen evidence that it works.  If you have access intermittently, you might want to try the following first.  See:

https://www.reddit.com/r/HomeKit/comments/b72vii/how_i_completely_fixed_not_responding/

I found on my router  (Asus RT-AC3100) the key setting seemed to be IGMP snooping.  Setting this to Enable has made AirPrint stable.  You’ll probably have to hunt around to find this setting on your specific router.  Recommend rebooting the router afterwards.  Hope this helps.
