High Sierra & printing PDF with Preview = problem

I followed the suggestion by TXHaflaire in

macOS High Sierra 10.13.2 - Finder issues when copying files in mounted shares | Discussion | Jamf Nation

As Admin in the terminal, I created a file /etc/nsmb.con, with following content:

[default]

protocol_vers_map=2

After a restart, SMB3 is not used anymore, only SMB2. I have not (yet) seen anymore "Unable to handle AUTH_INFO_REQUIRED” messages in the CUPS print queue, in http://localhost:631.

Though this sounds like one of the Xerox filters is crashing, and there should be info on which one in Console in the User Reports section. What version of 10.13 are you using?

February 2018 -- we have the same problem too. Once the job log, pasted below, hits 500 it stops printing. I will be discussing with our Xerox network admin as well. I'll report back if we get anywhere. I would LOVE to know if anyone has uncovered a solution. We are later to the game in updating to the newer OS, and in this case, I am thankful for that.

We have this issue too at the university I work for. It involves Sierra and High Sierra. The symptoms are:

• the print queue will state "filter failed";
• the printer will pause;
• upon trying to resume the printer, the queue will send numerous failed login attempts to the print server;
• then the printer has to be removed from the setup and added again before it will work.

This is an issue that happens with some, but not all deployments. We replaced one computer for a client but the issue happens on the new computer (Sierra) as well. Every time we think we have a solution, it fails. The latest test is using LPD printing. We use Xerox printers with Papercut, but the Papercut client is not necessary on the computer since most users have only one account.

Thanks,
Luis

I thought as much, given that there seems to be an authentication error.

I use a printer connected in the same way at my workplace.

If there was a change of your password (IT here forces people to change passwords yearly), the problem can be that the old password remains in the keychain.

Open Keychain Access, and search for a password for that printer and delete it. Then try to print. It should ask your for a password this time, and hopefully print.

I have exactlythe same problem. Moreover, after reading your post, I now think the problem might be related to the printing environment at my university, because I suspect we work at the same university. I remember hearing from the IT service department that someone else at my university reported the problem I have, and it was described in exactly your words. So I take it you reported that problem at Utrecht University.

I've done quite a bit of searching online, and the only other report of this problem with 10.13 that I have found is yours. Makes me think this is likely UU-related and not just an Apple/Xerox issue.

Update: I looked at the problem with Mac specialist in the Beta faculty this evening and found out the following. Although 10.13 reports each print job to have stalled and logs authentication errors, the print job actually arrives at the Xerox printer server complete and ready for printing. I realized this when I logged on to the printer and noticed that it listed all of the print jobs that I had sent to the printer server in the past days. Each of them printed fine. So, it looks like 10.13 is either misreporting authentication errors, or is reporting errors that have been addressed via other means. At least in my case. Can you confirm that this situation holds for you too?

I have the same experience, the jobs do arrive at the printer. However, you have to manually remove them from the queue and if you ten or more jobs in a row the next one only starts when the previous job has been removed.

Hi guys,

I would like to chime in, this time from Aalborg University.

We seem to have exactly the same printing setup and similar printers.

I have also done a clean-install for the OS (twice by now), followed by an install of a Xerox wc7835 on the network with exactly the above described setup situation. But in my case, the problem always came back eventually after a couple of days.

Jan Willem, is your printing still working smoothly?

I can easily recreate the problem, time after time.

Simply print, than ask to see in Preview app.

Then save anywhere and everything freeze...

Force quit will fix that but when you do that 100 times everyday, it's a pain.

I have found (in a script) that every minute a check about the status of the printer is done (by the Xerox software ?). This request is not authorized so the check will stay in cups local printer queue.

For example:

Tue Dec 19 16:22:27 CET 2017

Tue Dec 19 16:23:28 CET 2017

Tue Dec 19 16:24:30 CET 2017

Tue Dec 19 16:25:32 CET 2017

Tue Dec 19 16:26:23 CET 2017

Tue Dec 19 16:27:25 CET 2017

Tue Dec 19 16:28:26 CET 2017

etc etc

After one hour you have 60 jobs and after one day 24*60=1440 jobs.

Question: how do we stop this status-check?
