HP laserjet M15w not printing on iMac but ok on iPad

[thegubman]

Hello today I have been unable to print on my HP laserjet pro M15w printer using my iMac operating system 10.15. I can print a test page OK and print from my iPad. I have changed nothing. The wifi blue button is lit OK and the computer is showing the printer to be connected. Very frustrating and odd. Am I going to have to uninstall the software and start again? No problems for around a year until now. Any advise? Thanks Graham

Hi @thegubman

Welcome to the HP Support Community. I'd be happy to assist you

Due to the current global COVID-19 situation, we're seeing an influx of customers coming in for support. We appreciate your patience.

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.

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.

Have a great day!

For some reason the printer setting had changed. I am able to now print on my iMac when I select HP LaserJet M14-17 but not when HP LaserJet M15 is selected. Which is odd, but works OK.

Thanks Graham

Laserjet M15w is a series of HP LaserJet Pro M14-M17 Printer Series.

You can try renaming the printer, or you can try the below steps -

Try updating the printer's firmware - HP Printers - Updating or Upgrading Printer Firmware 

 Add the AirPrint printer to the Mac printer queue

Confirm you are using AirPrint by adding the printer in System Preferences.

1. Click the Apple menu, click System Preferences, and then click Print & Scan or Printers & Scanners.

   Figure : Example of the Printers & Scanners window

   

2. 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.

3. Confirm AirPrint or Secure AirPrint displays in the Use or Print Using menu, and then click Add.

   Figure : AirPrint displays in the Use menu

   

4. Open a document or photo, click File, and then click Print

Keep me posted!
