hppostprocessing.bundle problem when printing

Using the Generic PS driver worked for me as well.

My HP2025dn has a duplexer and after updating the printer in this way, it still works.

I hope HP and Apple can find a way to avoid such issues in the future.

MacBook Pro Late 2016 / Catalina 10.15.7

Printer HP DeskJet 2132 (I know it's not a wireless)

This helped in my case:

1/ removed all software I installed for my HP 2 years ago

2/ removed my printer from Preferences/printers/scanners

3/ installed HP Printer Drivers v5.1 for OS X from support apple com

Started printing a document without even adding a printer. My Mac just got it all by itself.

Hope it helps.

I found someone who had the same printer as me on the discussion thread. The instructions were to delete the computer and then add it in using the IP address rather than selecting the printer from the list, then from the click down options LPD and then generic postscript. It worked for me. Quite a few threads have said Apple are wanting you to use AirPrint so it might be worth seeing what people have written about that if the other solution doesn't work.

Follow these steps if you’ve got this problem with macOS Catalina

Step 1. Reset the printing systems in macOS Catalina

It’s very easy to reset the printing systems in macOS, and doing so can resolve all manner of printing problems on your Mac. If your printer still doesn’t work, this might be the solution you need to use to fix it.

From the menu bar, go to  > System Preferences > Printers & Scanners. Control-click in the sidebar that lists your printers. Choose to “Reset printing system…” then confirm you want to “Reset” in the pop-up.

Resetting the printing systems removes all your printers and scanners as well as clearing various behind-the-scenes files. Reconnect your printer afterward, as you did in the previous step.

Step 2. Remove the printer settings from your Library

The Library folder is used to store system files, preferences, and users’ information.

Your Mac stores all manner of system files, preferences, and other settings in a hidden folder called the Library. When an app misbehaves, sometimes it’s because these files are corrupt. 

You can usually fix this by removing the relevant files, forcing macOS to recreate them. However, you need to be cautious before removing anything from your Library. These files can affect the way your macOS works.

Make sure you only touch the files in the folder listed below. And don’t move anything to the Trash until you’re certain your Mac is still working.

How do I remove the printer settings from my Mac’s Library?

1. Open Finder, select Go > Go to Folder.
2. Type: /Library/Printers/ and hit enter.
3. Create a new folder called “Printers Content” and move everything from the Printers folder inside it. Now drag that folder to your Desktop.
4. Reconnect your printer and try printing again:
   1. If it works: Move the “Printers Content” folder to the Trash.
   2. If it doesn’t work: Return the “Printers Content” folder to the Printers folder and empty it.

Did these steps fix your printer problems on macOS Catalina? Let us know in the comments what did or didn’t work for you! And be sure to contact Apple Support directly for one-to-one technical support if you need more help.

The problem appears to be with the HP Printer drivers. HP will need to update their Mac OS drivers to support 10.15.7. If you are running OS X v. 10.15.x change the printer driver on any HP printer to use "Air Print" or Secure Air Print" and you'll be able to print again. You may not be able to use the full functionality of your HP printer (Page setup adjustments, Duplexing, etc) but you will be able to print.

HP! Get on the ball already and fix your drivers!

This worked for me to regain printing ability. With a fixed IP address for the printer, I added a "new" printer with that address, using IPP and configuring as a Generic PostScript Printer.

Have a look here:

All I had to do was go out and install new drivers for my printer on my iMac and all is great and printing.

I can't print from any of my Macs to my network printers this AM (HP and Xerox). I can print from my iphone. I can ping and access the printer from a browser.

I think the silent updates from last night hosed printing. You can see several printer issues crop up over night in the forums (printers that works now don't, "software name" will damage your computer, network printing that won't work).

I expect more posts to follow today. I've been in IT my whole working career. I've been through the standard checks. Apple needs to fix this.

See response from lincoln174 In the print dialog box that that shows up when you try to print, choose ADD PRINTER and it just sort of reinstalls the printer you are using +the number 2. It's working for me!



If you open a document (any document) and choose print, then in the dialog box where the offending printer is showing, Click on the dropdown to choose a printer and pick ADD PRINTER. Click on the name of the printer and it will populate the NAME with the number "2" . Leave location blank and under "USE" pick generic Post Script Printer. Click Add and make this your default printer. That should work-at least it did on mine.

As said:

A link to updated drivers on HP's FTP site has been posted here a number of times. I've also had a notification of 'new' v5.1. drivers in System Preferences > Software Updates, which seem to work.

I even called HP tech support again as I have an extended support plan. They gave me a direct line so no longer spending time on hold. They said I would have to wait for a patch or other solution from Apple and HP. He said they have been flooded with similar calls. That I should continue using air print for now.

In my first attempt, I've deleted the HP-Files from library. After installing the 5.1 driver package, the pop ups continues. So I put the old files back to the library.

Today I download the package again, install it and it works. I did it again, because a tweet of Thomas Reed pronounced an Apple update for the HP drivers.

I got this from HP support:

This package has updated certificates, which is what is likely causing your problem.

Download, install, then, if necessary, uninstall and reinstall your printer!

You're welcome!

But I cannot download the file. It stops at 40+ megs. The file is over 100 megs.
