Error with new Sequoia OS 15.3 "Printer not found"

Many thanks. I’ve tried most things - I can ping the printer over the wired connection, access the printer’s web server from a browser, reset the printing system, etc. If I add it via IP as an IPP printer it works, just not as AirPrint. The printer has a static address. Have rebooted everything. Really seems to be an issue that was introduced with 15.3.

"Unable to communicate with the printer at this time". This is the message i got when i'm taring to add my DCP-L2540DW PRINTER. what to do to solve this problem?

Hello, I have a Macbook Air M1 running Sequoia 15.3, and a Canon Pixma G3270.

I have found that MacOS does not find the printer via a 'basic' Canon install.

However, if I install it via IP and declare it an Airprint printer, it works if it is the 'default' printer.

Apple update 15.3.1 fixed the issues I was having.

Did chat with Apple. After trying a few things found that printers connected by usb even when not connecting by wifi (duh - I know) which showed it was not a printer problem. So tried a reset on printers.

The issue cleared up when I disconnected from wifi (which made job in print queue come out immediately), told it to forget network, and then searched for network again. When reconnected to network it showed all printers as present and working.

I have Epson WF-3720. Printer worked fine until I downloaded Sequoia 15.3. Error message says printer is offline.

Printer is online for my Iphone which works fine.

I've turned on/off Mac, printer and reset modem, so I wonder if this is a bug on new OS?

" new Sequoia OS 15.3 " from what previously you do not say(?)

Printer & scanner are typically the first causality in any macOS Upgrade, learn what to do...

I see your printer is listed in the AirPrint—

If it is listed as AirPrint printer, delete the existing printer, and add it again, select AirPrint.

“Print Center.app “ replaces all of the old printer icons. Everything should work as expected.

In Print Center, use the "Printer -> Add to Dock" menu.

if in doubt from the Spotlight Search:

This is also happening for an HP 5740 accessed via Airprint 3.0. It has worked flawlessly until the most recent update to Sequoia OS 15.3. The Macbook has always run the latest release of MacOS.

Now the Macbook sees the printer as offline. Other devices are able to see it and print to it. It seems to be more likely to happen after the Macbook resumes from sleep.

• Resetting the Print System does not help.
• Restarting the printer does not change the behavior.

The only fix I have found is to reboot the Macbook.

I have an Epson WF-4820 and since I loaded MacOS Sequoia 15.3 my scanner dies not connect. Printing though works. Any suggestions? Its a WiFi link

I've got the same problem with my HP and my Canon printers. Started just today, or at least that's when I noticed it. I installed the newest OSX 15.3 update a few days ago. So it's in the update. It screwed up printing on my MacBook and my iMac.

I just set my Canon to connect over AirPrint vs. the wired ethernet connection, and I can print from both the iMac and the MacBook to the Canon printer when it's a Wireless connection. But both printers show the as Offline when its an ethernet connection. My HP printer doesn't have Wireless connectivity, just ethernet.

So it seems to me that the OSX 15.3 update did something to screw up printing over ethernet connections.

Apple just posted a new update for Sequoia. Its 15.3.1. That seems to have fixed it. I did have to turn off my 2 Mac devices and reboot my cable and routers. The Network was showing an IP address for those 2 Macs of 169., etc. so they weren't able to connect to the Network. A real pain.

I have the same problem with a Canon Maxify GX7050, trying to print from an M1 Max running 15.3.1. Have had the printer for over 1 year and all worked fine until recently. Printer is wired and on the same subnet as the Mac. Cannot add it as an AirPrint printer over wired connection but can over WiFi.

Go into Settings/Network and make sure that the wired/ethernet connection is Green and not Orange or Red. If it's not Green, then the DHCP may be screwed up like mine was and it was not finding the local network. Maybe shutting down the computer, printer and rebooting the internet modem and the router, and then restarting the computer and printer will fix it. I also unplugged for a few minutes the Ethernet Switch that I use and that may have cleared out the bad IP address.
