Macbook Pro wireless LAN scanning

HP Deskjet Ink Advantage 3540 e All in one
macOS 10.14 Mojave

 Since changing the printer to WiFi connection on our LAN ( from USB cable to my wife's Windows machine ) the Mac book doesn't 'see' the printer usingi HP Easy Scan ( which it did before the change ) or Apple Image Capture .

However I am still able to print using the Macbook Pro as in the past connecting via my LAN network. 

Any Suggestions ?

@Patprinter1, Welcome to HP Support Community!

 

Once launching HP Easy Scan ensure there is no alert mark near the listed scanner name.

If there is such click the Presets menu and press on Browse Scanners, then select your printer and try scanning again.

 

If the same remains try the following:

From your Applications folder or its HP subfolder delete any existing HP Scan or HP Easy Scan application, delete it by moving it to trash, then empty the trash.

Next, install the latest HP Easy Scan below, it will be installed within the Applications folder:
http://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Installations/Essentials/hp-easy-scan-1_...

Finally, ensure your drivers are up to date by clicking the Apple icon, select About this Mac and then press Software Update.
Click Store on the top menu bar, click Reload Page, click Update All if any updates are available.

 

Keep me posted for further assistance.

Macbook Pro wireless LAN scanning

Performed all suggested steps but unfortunately did not solve the problem ,  The fact that both HP Easy Scan & Apple Image Capture show that there are no devices attached  suggests that the problem is not  a Easy Scan software problem but a WiFi communication problem , but what I don't understand then is why I'm still able to print via WiFi.

HELP !

To be able to assist you better, I would like to know the following:

  • Is your router dual-band enabled i.e., both 2.4GHz and 5GHz?
  • What is the distance between the router and the printer?
  • Is there any antivirus software installed on your computer?
  • 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.

 

Keep me posted for further assistance.

Thanks for replying. The connectivity seems to be fine.

To isolate the issue further, try using HP Smart App to scan. Refer to the document HP Printers - Using the HP Smart App (Mac) for help.

I would suggest you disable your security software temporarily to isolate the issue.

 

Ensure that the printer is up to date with its firmware and Mac is up to date with its software. If you are unsure you may use the links below to update the printer firmware and Mac software:

Update printer firmware

Update software on Mac 

 

Remove and add the printer

Click the Apple menu, and then select System Preferences.

Depending on your operating system version, click Print & Fax, Print & Scan, or Printers & Scanners.

Click the name of your printer, click the Minus sign, and then delete the printer.

 

Select printer and click the minus sign

Click the Plus sign, and then click Add Printer or Scanner.

Click the Use or Print Using box, and then select AirPrint

 

Select AirPrint from the Use menu

 

Click Add to add the printer to the list.

Try to print and scan.

 

Keep me posted for further assistance.

I checked - Printer & MacBook software are both up to date.

I removed the printer using System Preferences.

However No printers are available to select one to add

The message shown is Press + sign to set up a printer ( see attachment ) 

The next window ( see attachment ) allows one to search for a printer , but finds none at all 

The only way to install the printer is via Set up a printer & entering the IP address  (see attachment)

The HP printer is then successfully installed ( see attachment) & the Mac Book will print to it but not scan !

UpDate : After some Internet research It appears that Apple requires Ipv6 to be set to 'Link-Local only' not Automatic for Bonjour to be active. This is in Network in System Preferences.  

I have done so , I then set up a new 'Bonjour ' device and now HP Easy scan can 'see' the printer as a new Scanner.

However I now get an error message communicating with the scanner.
