So if you have received similar kind of errors while trying to print a document with your connected HP printer from Mac, then try out these two proven methods to fix this issue.

Method # 1: Completely Remove HP Printer Driver & Re-Install Manually

Step # 1: Open Settings on your Mac.

Step # 2: Go to System Preferences -> Printers & Scanners.

Step # 3: Choose your installed HP printer from the list, and then click on “minus ” sign at the bottom left to remove it.

Step # 4: Once done with removing the printer, it is time to remove the HP drivers from library.

Step # 5: For that, open Finder. Go to “~/Library/Printers/hp

Step # 6: Delete the whole HP folder and clear the trash.

Step # 7: Now, you need to re-install your printer. For that, again open Printers & Scanners from “System Preferences” and click on “Plus +” sign this time to re-add your printer.

Method # 2: Update Printer Drivers Using HP Easy Start

If your HP printer is supported by HP Easy Start utility, then you can update it directly by following the steps below:

  1. Download HP Easy Start (latest version)
  2. Install it, and then follow on-screen instructions to add your printer.

If you already have your printer installed, then you would need to re-install HP Easy Start after its installation, and then start-over. Here’s how:

  • Open HP Easy Start
  • Once it is launched, click on “HP Easy Start” in macOS menu bar.
  • Click on “Uninstall HP Software”.
  • After successful uninstallation, disconnect your printer from your Mac.
  • Re-connect it again, and then star the re-install of HP Easy Start.

Method # 3: Download HP Printers v5.1 (Latest) Drivers and Manually Install

If the problem persists or you were not able to update your HP printers drivers using automated utility, you are still covered.

Apple has recently released the updated HP printers drivers (version 5.1) which include patch for these errors, along with covers almost all HP printers.

Method # 4: Look for Suspicious Files and Remove Them

If somehow deleting and re-installing your HP printer does not fix this problem in macOS Catalina on your iMac, Mac or Macbook, then you need to check your system for any suspicious files.

Here’s how:

Step # 1: Open Finder.

Step # 2: First, go to “~Library/LaunchAgents” and delete the suspicious or most recently added file to bin.

Step # 3: Repeat the above steps for these 2 directories as well:

  • ~Library/LaunchDemons
  • ~Library/LaunchAgents

In my case, the aforementioned method # 01 worked and I was able to get rid of this HP printer error on my Macbook Pro 2015, running on macOS Catalina 10.15.5.

If in case you are still having trouble with printing using your HP printer connected with Mac, or have any question[s], let me know and I will try to get back as soon as possible.
