hppostprocessing.bundle problem when printing

Just tried to print to my HP Color LaserJet Pro MFP M277 dw and got a message pop up on my iMac

“hpPostProcessing.bundle” will damage your computer. This file was downloaded on an unkown date.

With a tick box to Report Malware to Apple to protect others.

I have had this printer for a few years and it has operated without problem.

I am running Catalina 10.15.7 on iMac17,1.

NB I can see from the information below that Report Levels was added at 12:16 yesterday 22 October 2020. I know nothing about this.

Hey there! I’ve seen this after the update as well, I think HP drivers are out of date and need to be updated to work. Here’s what worked:

First, if updating the software manually doesn’t work:

Open Finder, on the top menu hit Go > Computer > Macintosh HD (Usually) > Library > Printers.

Save (If you need to, and Delete the HP folder from there, (You’ll notice when clicking “Show in Finder” when you get the errors, these are where the files are, in this case old, outdated drivers and files).

Once deleted, open System Preferences > Printers and Scanners.

Right click (or Control click) select “Reset Printing System”, (This will delete any existing Printers and Scanners).

Once done:

If USB Printer, dis connect/re connect, you may see the option to “Install” the new HP software.

If a wireless “AirPrinter”, just hit the “+” sign to re-add the printer and select “Add”.

Do a test print to make sure it’s working again!

This is Gatekeeper, Mac’s security doing its job, most likely if you’re getting that error message, it’s a good thing to remove the older software.

Hope it all goes well!

It doesn't work to install the HP driver on Big Sur. It says "This volume does not meet the requirements for this update."

Apple needs to solve this problem, is just disgusting that for the past 2 months i can't print without the aid of a drive on another computer.

It is not fine at all.

I removed old files then downloaded from this link. I still am getting the same error messages that it will damage my computer. The error points back to the files just downloaded from this link.

This addition was not initiated by me. Suspect that HP maybe the problem.

BTW I tried to print from IPad and that was not good either - the same message popped up on IMac

This is happening with our entire school district at the moment with HP printers, our Ricoh printers are just fine. Started late yesterday afternoon. Using the generic post script software option as the work around for now. Just have to fix this on 385 more Mac Books.

I'm seeing all of the same problems described above and throughout this thread, on several generations of Mac hardware, on both OS 10.14.6 and 10.15.7. HP Print drivers are broken all around. I'm seeing similar complaints on the HP support forum.

My particular printer, a Color LaserJet CP1518ni is connected by Ethernet. I can still see the web page served by the computer, and I can use that to print a test page (which is generated internally in the printer), but I cannot print a test page from the print queue app--it spools and nothing happens.

I have exactly the same problem on a MacBook Pro 2018 on a Catalina 10.15.7. The only thing I have installed lately, before the last time I printed, is the latest Adobe Creative Cloud version 5.3.1470 with the latest Adobe's software. I am not sure though that this is the cause of the problem. I have not made other changes for weeks. Even reinstalling the printers does not solve the problem. Both of the M553 printers I am using are on a network. This problem came out of the blue.

I deleted the printer then added it using the IP Address and LPD plus Generic Postscript and eureka! I can print again. What a weird random thing to happen. I am glad I found this post as I was already thinking I needed to buy a new printer.

If your HP printer supports AirPrint, go to SystemPreferences, Printers and scanners. Select the printer and remove it by clicking on the -(minus) sign (unlock the padlock if necessary). Then click on the + sign and add it again, using AirPrint https://support.apple.com/guide/macbook-air/use-airprint-apd98b1f28d0/mac
