I see this error when sending jobs to a standard queue shared via SMB or CUPS
I see this error when sending jobs khổng lồ a Mobility-Print-published queue và my environment uses both plovdent.com và Mobility Print
This message is often wholly unrelated khổng lồ plovdent.com. Usually, if you see this error, it is about the print queue’s OS-level authentication instead of plovdent.com
Try the easy options firstSometimes this issue is just a hiccup the Mac experiences when connecting to lớn a shared queue. Click the refresh button & see if it prompts for credentials.
Confirm correct cài đặt of the print queue connectionMake sure that there aren’t any spaces or special characters in the printer name. That is khổng lồ say; our recommendation is only to lớn use alpha-numeric (numbers & letters) characters when naming your vps print queues.
If you’ve successfully verified the information above, it might be worth recreating the printer on the client machine. For more detailed information kiểm tra out the relevant resource below:
Try a different driverSome customers have found that using a different driver resolves the issue in some cases. It’s worth checking the manufacturer’s website khổng lồ see if there’s an updated (or alternative) driver.
Force the Mac lớn request authenticationIf refreshing the job doesn’t bring up the credential prompt, you might be able to lớn force the prompt khổng lồ show with the following steps. However, if the lpadmin command doesn’t help, fear not- there’s a lot of KB article left. This option should only be used by administrators comfortable using the Terminal Application in macOS.

If you see this message when printing with Mobility Print
As is the case without Mobility Print, the most common cause of the “Hold for Authentication” error is entering the username & password incorrectly. You should first attempt to re-enter the credentials by clicking the refresh button. If the problem was due khổng lồ an incorrect username or password, the job should go through with the correct credentials after reentry.
Per-Job Authentication with Saved credentials
The message can also appear if the Mobility Print queue has Per-Job Authentication enabled & the user has peviously saved their credentials for printing in the Keychain. With credentials stored in the Keychain, the prompt for won’t pop up, but if opened, the print queue window shows “Hold for Authentication”. While annoying, this does prevent the more significant problem of a user accidentally saving their plovdent.com credentials on a shared device.
A) Disable Per-Job Authentication - this will not be practical if your users nội dung devices & you want khổng lồ prompt for credentials with each Mobility Print job
B) Delete the credentials from KeyChain Access - Remove the credentials, cancel và retry the job to continue using Per-Job Authentication.
An apostrophe in the username
The apostrophe shortcoming is inherent khổng lồ macOS whether the user authenticates with their apostrophe-enabled username on a print queue advertised from Mobility or a print queue published directly from an AirPrint-enabled printer. At the time of this writing, we have yet lớn determine whether this lapse is due khổng lồ CUPS, macOS, both, or something else entirely.
A) Refresh and re-enter the same credentials - As a workaround, this allows the job to lớn go through, but every print job sent will need this.
B) Turn on Username Aliasing - Enable username aliasing to add a username that excludes an apostrophe. Bear in mind, you will need lớn instruct your users to use this alternative username for Mobility Authentication.

A rogue Mobility server
In rare cases, an unintended Mobility Print server may make its way onto the network. This can happen when a user (we’ll hotline them Bob) is searching for the client-side applications, but stumbles upon the vps installs for both plovdent.com & Mobility Print. By accident, Bob has made their machine both a plovdent.com Application Server, và a Mobility Print vps (this issue will not occur with Mobility Print without plovdent.com installed to lớn as it will not require authentication). Bob eventually adds the printer that’s been published on the true Mobility Print Server, and so it gets republished automatically by Bob’s rogue Mobility Print server.
The pickle in this case is that if another user has connected to the queues automatically published by Bob’s computer, any job sent to this rogue queue recieves “Hold for Authentication” on their macOS device or “Incorrect name or password on their quả táo device.
