The Sonoma 14.4 update is causing more problems, this time with printers by removing or corrupting the drivers needed to print, and there is not yet a comprehensive solution to the issue.
We recently learned of an issue where updating macOS to Sonoma 14.4 caused some USB hubs embedded in monitors to stop working. Now, it looks like macOS Sonoma 14.4 is breaking printers, too.
Reports have begun rolling in on Reddit and the Apple Community forums, where users note that after updating their Macs, they no longer could print.
According to a post on Reddit, it seems that macOS Sonoma 14.4 removes the core CUPS software, leaving no way for the printer and Mac to interface.
Redditor nicover84 says that, according to some JAMF discussion groups, the issue could be caused by Microsoft Defender. Some users say that granting full disk access to com.microsoft.dlp.daemon in Privacy & Security settings either locally or with a JAMF config profile fixes the problem.
Initial reports seem focused on users with HP printers. Commonalities between the reports aren't clear — Microsoft Defender isn't the only cause, nor is the use of JAMF mobile device management software.
For the time being, if you print routinely from your Mac it may be wise to wait to update if you haven't already. The update in question was released on March 7.

There you go using the "break" word again.
Are the printers themselves actually broken, or just the functionality to make them work? That's an important distinction.
We love you, but let's stop with the clickbait headlines, eh? :D
Sonoma 14.4 is off to a rocky start.... I hope my printer still works!
No problem with an Epson WF-3620 attached via a 10 year old USB hub to a MBP 14" M2 Pro, using macOS 14.4 (downloaded early this morning). No problems with a 24" Lenovo monitor attached by HDMI. No problems with two iPod Classics (attached via a USB hub). Update from 14.3.1 seemed to take longer than several previous updates, but otherwise, nothing to complain about.
... I had to delete & reload my HP & Brother printers with Ventura 13.6.5 ...
