I have a mac book pro and an HP Envy 5530 printer up until about 2 weeks ago i could print wirelessly with no issues. then it started where the print queue always said "stopped" and would never print (canceled jobs restarted etc). I think removed it downloaded HP Smart Print (3 or 4 times) now when i try to add the printer i just says "an error occurred while trying to add printer" or "cann't communicate with printer" I can still print from my iPhone and my work computer so its something between my mac book and printer. Suggestions?
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.
I'd like to know the following to isolate the issue further-
1.) Are the printer and Mac connected to the same network?
2.) Is your router dual-band enabled i.e., both 2.4GHz and 5GHz? If yes, make sure the dual band has different SSIDs for 2.4G and 5G networks.
3.) What is the distance between the router and the printer?
4.) Is there an antivirus software installed on your Mac?
5.) Could you perform a ping test using the Mac Network Utility and let me know the results? Use the printer IP address to perform a ping test, the printer IP can be located by selecting the wireless icon on the printer display.
The wireless status menu on your Mac should also give us quite a lot of information that would help us identify the issue. You can press and hold option-click the WiFi icon and then use shift-command-5 to take the screenshot. Press the space bar when the icon turns into a camera. Share the ping test results and the screenshot with us.
Also, check with your Internet service provider if your router is able to forward 'Bonjour packets'. Bonjour locates devices such as printers, other computers, and the services that those devices offer on a local network using multicast Domain Name System (mDNS) service records. The software comes built-in with Apple's macOS and iOS operating systems.
Hope this helps! Keep me posted.

Check if your printer name displays in the Printers list, and then do one of the following steps.
If your printer is listed, remove and re-add the printer to confirm it is set up for AirPrint. Click the printer name, click the minus sign to delete the printer, click the plus sign , click Add Printer or Scanner, click the printer name and then continue to the next step.
If your printer is not listed, click the plus sign, click Add Printer or Scanner, click the name of your printer, and then continue to the next step.
If your printer is not listed in the Add Printer or Scanner window, go to the Frequently asked questions in this document to resolve connection issues, try to add the printer again, and then continue to the next step.
