This is my second HP printer that is having this issue....
New HP Envy Photo 7855
Mac OS High Sierra
Iphone X
Ipad Mini
Ubee Router/Modem combo
Hello,
I have tried every step I have been able to find on the web, through support, and on the TWC/Spectrum forum. I can connect the printer to my home network, everything will run fine, can airprint and wirelessly print for a brief period of time. May be an hour passes or overnight, and the printer is no longer communicating with the network. I will get the "No airPrint Printers found" message on the iphone and ipad, the Mac will show that the printer is offline.
I can power the printer off and put the iphone on airplane mode, come back up and they will connect again briefly.
I have done the following (not necessarily in this order but all have been tried at various times):
1. Printer is connected to wall outlet
2. I have reset printer defaults and reloaded-Did not help
3. I have assigned a static IP to the printer-Did not help
4. I have assigned a static IP to the printer within the Ubee modem-Did not help
5. I have changed the modem IP start and adjusted the printer IP outside the range-Did not help
6. I have made sure the modem channel was one without a lot of interference-Did not help
I am really at my wits end and would greatly appreciate any other suggestions someone may have. This just seems really crazy to me. Someone suggested that the printer must be connected by ethernet to the modem, but I am not sure if you can still print wirelessly then?
Thank you!

These settings are for setting up your wireless or wired printers to:
* Stay connected to your router
* Fix printer ‘offline’ status
* Wake from sleep mode
* Speed up wireless printing
While DHCP is convenient, devices such as printers (wired and wireless) should always be assigned a static (fixed) IP address manually to avoid conflicts on your wireless network and MUST be outside the DHCP address range of the router. This is because printers are the only external devices that do not have the ability to automatically interrupt the router for a new DHCP address once the least time expires. Again, do not have the printers static IP within the DHCP range of the router as this is against Networking 101 rules and will confuse the router. Make things simple – In the router, set starting DHCP address range 192.168.1.100 (or 192.168.0.100). Ending DHCP address range 192.168.1.150 (or 192.168.0.150). Set Printer Static IP to 192.168.1.10 (or 192.168.0.10).
After setting the static IP, the computer(s) must be updated under Printer Properties/Ports to show a Standard TCP/IP port with the printers’ new static IP address.
1. Set a static IP in the printer outside the DHCP range of the router (check your manual). This Static IP is important as DHCP IP addresses will change upon different power up sequences of your devices. You always want your printer to come up with the same IP address all the time. See how to do this here:
This is for Linksys routers but can be used for all routers. Verify your DHCP range and change this first if needed. Then after setting the static IP in the printer, the computer(s) must be updated under Printer Properties/Ports to show a Standard TCP/IP port with the printers IP address.
To see why this problem exists and how to fix it, watch this video here for Windows. Scroll down for MAC information.

How to set a Standard TCP/IP port. This is important.
a). Click Start/Devices and Printers. Right click on your HP Printer. Select Printer Properties. Select the Ports tab at the top.
b). Select Add Port. Select Standard TCP/IP Port. Select New Port.
c). Follow the Add Port Wizard. Under Printer Name or IP Address, input the Static IP address you just set from the above information. Example: 168.1.15. The IP address will be copied under Port Name. This is OK to leave this alone or you can put in your Printer Model.
d). Select Next and Finish the Wizard.
If you create a TCP/IP port without a static IP above, you may lose your TCP/IP connection and have the same issue. This is because your network has powered up differently giving you a different DHCP address to the printer that does not match the TCP/IP address above. This could occur at anytime just like the video shows.
For MAC PCs perform the above Static IP setting in the router and then watch here on how to perform your IP setting for MAC computers.

By performing the above, the printers Embedded Web Server (EWS) will now work all the time by going to your Printers Static IP address in your browser.
2. Verify in the printer that 'Auto Off/Sleep/Energy Saving Mode' is disabled and/or the System Mode Time Out is set to zero (0) if your printer supports this. Use the Embedded Web Server (EWS) by going to the printers IP address in your browsers address bar, click Settings Tab/Auto Off, or use the Printer Assistant, Printer Home Page (EWS). Also check your Printer Properties. This feature is automatically disabled when the printer is connected to a computer or mobile device, a network, or a fax line (if supported). However, you may not find this setting.
3. If the printer supports and has IPv6 enabled, disable IPv6 in the printer.
4. Make sure printer is plugged directly into a wall outlet and not into a UPS, power strip or surge protector. This may cause the printer to intermittently drop offline and disconnect.
5. Make sure your printer and router are at least 5 feet apart from each other.
6. Check the HP web site for your printer to see if there is a Firmware Upgrade that affects the wireless operation. If yes, update the firmware via USB cable only. Never wireless.
Additional steps to be taken if you continue to have the problem (if they are posted)…

Hello and thank you for this information. I have followed the steps and it is working for now. I hope it will continue to work after several hours. Would I need to do this same process in order to connect a Windows desktop or should that computer be able to find this printer?

How do I find this?

I am new to mac and tried to copy the pic of the port settings here please let me know if you can't see it.
