AirPrint not working after iOS 17 Update

Delaware, first, see my post above, it is an iOS 17 issue, but only affects older printers.

Second check if your printer has up to date firmware, contact your printer help desk. If your printer only supports AirPrint (Bonjour) 1.2.1 (2003 - 2015) it won't ever print from IOS 17.

Apple are not supporting AirPrint (Bonjour) 1.2.1 any longer (as far as I can determine), therefore any printer with this firmware version will not AirPrint from iOS 17. Period.

Also, just to clarify- I have a canon imageclass and I was able to update the firmware directly on the printer. I just googled the instructions and it walked me through regarding what settings to go to on the printer to update the firmware. Once it was done installing, I turned the printer off/on just so it would do a full restart and connect to my router and that’s when I was able to resume printing from both my iPhone and iPad.

Thanks, that was very helpful.

Same issue with Cannon printers on all devices after updating.

There have been reports that older Canon firmware is incompatible with iOS 17, but updating the printer firmware fixes the problem.

This seems to be the issue with older HP Laser Jet printers where photos and printing from the photos app are no longer compatible with the existing firmware. All other apps and files can print. The HP printing app is terrible but you can try that.

OMG. This thread dates back to Sept 2023. I wish I had seen it before updating my iphone last week. I don't have Norton or other antivirus software installed and my two Epson printers will not air print. Firmware is up-to-date, but since these problems go back to September, it would appear that Apple and Epson (as well as other printer manufacturers) are not listening. I can still print with my mac desktop which is so old that it is running Catalina. We were going to purchase a new desktop, but I am afraid that our fairly new Epson workforce printers will not be compatible. Help!

I honestly don’t think it has anything to do with anti-virus software- I don’t know why ppl are saying that. My canon image class is like 5 years old and when I updated the firmware OTA, it solved both printing problems on both my iPad and iPhone. I’m so surprised other printing manufactures aren’t falling in line. The quickest workaround I can think of is to basically airdrop whatever you’re trying to print from your iPhone to your MacBook. But sometimes the airdrop doesn’t work unless your MacBook OS is up to date. You would have to try and see first, but if the airdrop fails you can try turning off/on Bluetooth on your macboook before updating the OS. In terms of getting a new desktop, I doubt printing to your Epson would be a problem if the printer is fairly new. You would just have to download the driver from epson to your new MacBook or PC- whichever you buy. It’s found on the manufacture's website and you can often find the driver under downloads after you input the printer’s model number or serial number. That’s all I can think of until Apple gets their stuff together. They’ve started to make mistakes like this more often than they have in the past. Hope this helps.

I'm running a new M2 laptop printing to a really old Kyocera, just use IP printing, it's easy to set up and will print to any printer with an IP address. New desktop will work, its just earlier versions AirPrint that is not working that are causing issues with iOS 17, see my earlier post.

My printer is post 2018 and I had to update the firmware OTA in order to restore air printing on both my iPad and iPhone. MacBook was never affected. And until I updated the firmware, I would just air drop what I wanted to print to my MacBook. But like I said once I updated the firmware on my canon I just restarted the printer as a precaution and then I could resume air printing on my non MacBook devices. Also, the only additional advice I can give ppl is to ensure the printer and iPhone are on the same WiFi network. Like I can speak for myself and I have three - the main one, the 5G, and the network for my wifi extender. Sometimes it doesn’t matter, but usually when I make sure they are on then same one, I never have a problem.

did you try disabling it to find out? Or do you follow Aristotle, who believed that the human mind could deduce anything, and therefore experimentation was unnecessary?

I would tend to agree with you with most of these steps, but just a couple things to point out. First, I think deleting the VPN profile is necessary cause it seems the iPhone tends to turn it on when it feels like it at times. Like there was a time I opened my VPN app and it was clearly off and I even forced closed it, but Safari still thought I was in Canada. So I had to go into the settings and delete the profile, force close Safari and then it finally went back to the US. But I don’t think it necessary to remove the actual app. Because at the end of the day some ppl need to use their VPN- unless you’re using a browser like Brave that has a built in VPN. Can it cause problems? Yes, so if you feel that both the profile and app need to be deleted, then sure- but remember your VPN credentials if you don’t have them saved on the iCloud Keychain. Second, when “updating” the software on the printer I would say to ensure to update FIRMWARE on the printer. My printer is not fairly new, but I was still able to update the firmware OTA and after doing that- it solved all the AirPrint problems I was having on both my iPad and iPhone INSTANTLY. The only thing I would include is to check which wifi network your printer is connected to. Like I have three: the main one, the 5G network, and the network for my wifi extender. Sometimes AirPrint can’t find the printer if your iPhone and printer are on two different networks. I found sometimes it does, sometimes it doesn’t. But when I updated the firmware on my printer, I made sure my iPhone was connected to the network that I know my printer is connected to- and that’s also when everything started working fine again. So with regards to the iOS 17 update, it has seemed to do something to the phone where it cannot connect to printers with outdated firmware. Because it could still find my printer, but when selecting it - it wouldn’t do anything- but like I said when the firmware on my canon imageclass was updated, it instantly solved the problem. I think the problem for the ppl where this solution is not working is because their printer manufacturer hasn’t adjusted their software/firmware to be compatible with iOS 17 for iPhones/ipads. Yes, it’s true VPNs can mess it it, but at the end of the day the inability to airprint from iPhones/ipads has to do with the iOS 17 because it’s clearly incompatible with outdated or non-current software/firmware that is on the printer they are trying to print to. Because printing from my MacBook or PC to my printer was unaffected. This is an isolated iOS update issue that didn’t take into the account that the firmware on printers would need to be adjusted for it to be compatible. And apparently only some manufacturers got the memo and Canon is apparently one of them cause I haven’t read one other manufacturer that has made the necessary changes unless I missed a reply where it worked for on another manufacturer. Why only Canon? No idea.

VPN frequently creates more problems than it solves. But one important fact is that when you install VPN it configures itself to the specific hardware, iOS version and network that the phone uses. If any of those change it can break the VPN. So any time you change any of these you may need to delete the VPN app and profile, restart your phone then add them back (if you still want to use VPN) so it can configure itself to the new environment.

And the reason you delete the app is so it thinks it’s “new”, so it will reconfigure the profile. The app isn’t causing the problem, the profile is (as you rightly pointed out), but the profile needs to be reprogrammed.

Uhh yeah I did, I was on the phone for over a two hours with Apple who had me do everything humanly possible and even they couldn’t figure it out after being transferred to the second level support. I ended up figuring it out myself when someone suggested updating the firmware on my printer OTA. And guess what?? It solved the problem INSTANTLY. You don’t need a tech degree to figure out apple messed up and this is an isolated incident having to do with this iOS 17 update. You’re talking to someone who just knows about tech as a side gig/hobby from a young age- if you only knew what I actually do for a living.

Also, most ppl don’t have anti virus on their iPhone so I just thought it was a moot point. Plus it would by WAY more likely for the firewall attached to the anti virus to cause the problem than the actual anti virus - and that’s from actual experience. Yeah, worth trying, but it’s clearly not the issue. and I tried saying that in the most respectful way possible- I could have said “oh that’s a really dumb thing to think about”. But I didn’t, so I don’t appreciate the targeted sarcasm or the attempt to patronize me. I’ve been spending a lot of time on this thread trying to help people, not take shots at them. Also, I would think you would know that the only way to insult someone is if they actually cared about what you think of them . 🙄

Apple updated Bonjour, I think to resolve some vulnerabilities, and the printer firmware needed to be updated to support the newer version of Bonjour. My HP appears to have silently updated on its own.

Ok, the main issue that has been proven to cause the issue is not being prioritized. Updating the firmware should be included before restarting the printer cause if you read through every single thread- it seems to be the problem caused by the iOS 17 update. Like I pointed out- Apple had me doing everything humanly possible for 2 hours before I thought to update the firmware on the printer which again, solved the problem instantly. And I even think I had already put back my VPN profile before updating the firmware (it wasn’t on though cause I knew that would cause an issue potentially)- so that’s totally unconfirmed if that’s contributing to the problem. I would say yes, potentially it could be a problem because of what a VPN actually does. But this solution is not working for ppl who have printers by all these random manufacturers that no one has heard of, just the mainstream ones. Canon has seemed to have received the message, so I’m surprised HP users are still having issues. They either have printers that are so outdated that there are no available firmware updates (which DOES happen unfortunately) but for the newer ones- maybe HP has yet to reconfigure their firmware so all their printers are compatible. I have no idea how Canon was able to come out with an update so fast. Guess I just got lucky.
