Solved!

The disk you attached was not readable by this computer

HP Recommended
LaserJet Pro MFP M127fn
macOS 10.15 Catalina

My printer used to work, but ever since my OS updated, I havent been able to connect.

I have uninstalled the drivers and tried to use HP Easy Start, but my computer wont even recognize the printer at all.  I get an error message saying "The disk you attached was not readable by this computer".  

I have used other cables, and I have used different ports.  I have unplugged my printer.  

 

This printer does work on my PC laptop, but my  main computer is my MacBook pro, and having to email the files to myself to load on my super slow PC laptop to print is not the best use of my time. 

 

Can anyone help?

MY OS is actually Big Sur, but there was no option for Big Sur on this form yet.

I reviewed your post and I understand that you are unable to print after updating your Mac OS to version 11.

 

Don’t worry, I assure you I will try my best to get this sorted.

 

I recommend you follow the below steps and check if it helps.

 

  1. Go to https://ftp.hp.com/pub/softlib/software12/HP_Quick_Start/osx/Applications/HP_Easy_Start.app.zip and then click Download.
  2. After the software downloads, open HP Easy Start.
  3. Click File, and then select Uninstall HP Software... from the menu.
    Figure : Select Uninstall HP Software.
  4. Read any warnings that display, and then click Continue.
  5. When prompted, type your administrator user name and password.
  6. HP Uninstaller removes all HP printer software previously installed.
  7. If you are reinstalling the HP printer software, click Set Up New Device, and then follow the instructions to install the printer with HP EasyStart.

 

Let me know how it goes and you have a great day!

Hi thank you for responding, @The_Fossette !

So this is what happened.

 

1. I went to that link and downloaded it again.

2. After it downloaded, i opened it.

I clicked "I have read and agree to the etc" and pressed continue.

I was sent to Prepare printer for setup page and there was not option for me to click file anywhere to uninstall HP software.

So I plugged in my printer and hit continue.

I got sent to Connect and it listed my printer that was connected.  And then it asked me to install Essential Software and HP Easy Scan.

I successfully downloaded the files and was sent to Status and Alerts.  I hit continue.

I was sent to Add and Verify your Device and then Test Page.  The Test Page printed.  I tested Scanner, the scanner worked! 

Then i was sent to page Continue Online, which i did. 

 

Everything seemed to work. Thanks for your help! 

 

Even though I didnt follow the uninstall directions, your beginning helped for sure.  I think I uninstalled everything a previous day, and just left it after I got frustrated with this whole issue.  Thanks again.

I did the exact same thing on my wifes MAC as well, it it worked.

Still not step to uninstall anything, and no where to click "file" but that link definitely helped.

 

Thanks again.
