HP LaserJet Printer stopped working on my MacBook, after latest macOS Sonoma update.

@jblanchard1

I don't see crashes of dlpdaemon, I don't see "deny system-priviledge" in the console. Granting dlpdaemon full disk access doesn't help. It doesn't seem to have to do with dlpdaemon, but I'm not 100% sure. Something is killing the cups socket periodically, see here for more info: https://github.com/apple/cups/issues/6189

This is what did it for me. I had 2 printers installed and after going from 13.6 to 14.4 they completely disappeared. I could not re-add them. I gave com.microsoft.dlp full disk access and all of a sudden my printers re-appeared! Thanks so much for sharing this.

Hi,

We have 60 Macbooks which we manage via Jamf Pro. Since MacOS 14.4, all printing functionality on the Macs is broken. There are no printing drivers on the Mac and any printer related activity comes up with the error message "cupsctl: Unable to connect to server: Bad file descriptor".

Same issue on a fresh new Macbook or a factory reset one.

Cheers,

Filip

Has anyone actually reported this via https://bugreport.apple.com? I don't see any FB numbers reported in this thread. Please be sure to report issue via Feedback Assistant. Don't assume someone else has just beause there are others sharing your concern in a forum post.

>$ cupsctl

>cupsctl: Unable to connect to server: Bad file descriptor

same as on my MacBook.. which likely means that the entire printing system is broken

The printer problem is not an HP or Canon Problem nor a problem of managed or unmanaged macs, It is a Sonoma 14.4 problem and i hope they will fix it with a new update.

What you have encountered is not unusual. Apple does not develop its operating systems to conform to every printer's requirements. What Apple does is to provide OS requirements to all the various vendors who have equipment they wish to connect to and work with Macs, etc. Then the vendors must provide updated printer drivers (in this case) to meet those published requirements. This is how it has always been.

It's not a general problem. Otherwise this problem would be big in the media and the forums full of it.

Of course it's a Sonoma 14.4 problem, but it only affects specific installations. Finding out patterns (e.g., does it depend on managed/unmanaged etc.) might help finding a workaround. Or maybe even some Apple developer might read this and get helpful info.

My MacBook Pro (and my wife's), Sonoma 14.4.1 lost all connection to all the printers available to me, not just the HP printer. I'm not running MSFT defender, nor is my CUPS daemon corrupted or missing. I just can't print anymore.

I tried resetting the printing system, all I got was that I had to re-setup my HP printer... which doesn't ever complete. So I now have two laptops (one Intel, the other Apple silicon) that neither one can print.

We are stuck generating PDF's and sending them to our iPhones or iPads to AirPrint. I used to be the other way around, I couldn't print from my phone but the laptop was golden.

I've been using Apple products since I had a Macintosh IIsi. This is the first time where I have seen a problem that Apple seems to not even acknowledge exists. I've had some pretty esoteric issues over the years, and somehow Apple seems to fix even the weird ones. I've been trying to search for a solution and haven't seen anything.

If anyone has had better luck than me, please let me know. I can be an idiot at times, but this one has me stumped.

Might I ask those who deployed the update to multiple systems why you didn’t test before? When I worked for a very large company whenever a new Windows update was released it was weeks or months before we got the update installed on our work machines.

Thank you for sharing this. We ran into this issue at work recently and the fix posted here resolved the issue.

Our Jamf admin is pushing out a profile to update permissions for Microsoft Defender.

Exactly. Most users just come to complain and “me too” things without taking the initiative to report the problem. That’s likely because many users believe these forums are official Apple support. They are not.

Since you are directing your post to me, when I enter the cupsctl command in the Terminal, resulted in normal results ... and, yes, my Mac was updated to 14.4.
