Troubleshooting Find-Me Printing
“Help! We’ve set up Find-Me Printing in our print environment but we’re seeing print jobs disappear when users try to release them! Why does this happen and how can we fix it?”
PaperCut’s Find-Me Printing feature allows users to send print jobs to a one single print queue and release their print job at any printer. When it works, it can make users and sysadmins lives easier but when it doesn’t work it can be a frustrating experience.
Thankfully we’ve seen most of the things that can go wrong with Find-Me Printing and we’ve documented those reasons below.
This article specifically addresses scenarios where print jobs sent to a Find-Me queue will disappear, but regular print queues on the server work just fine.
First things first, we need to establish whether this is a problem with Find-Me Printing or printing to this printer/driver/server in general. To do so, let’s take Find-Me Printing out of the picture for a moment and try sending a print job to “destination” print queue on the server which is configured similarly (same driver, same settings, etc…). Does this print job also vanish? If so, see our article on Missing or Disappearing Print Jobs.
If not, continue below…
Sometimes we see that a step has been overlooked during Find-Me Printing Setup and now jobs are being inadvertently released to the wrong device.
You can check for this by looking at the Job log in the admin interface (log in to PaperCut as admin → choose Logs → Job Log). Find the print job in question and see if this was released to a different printer than the one which was intended. If that’s the case, you’ll need to revisit how Find-Me Printing is configured.
First, log into PaperCut and open the Printers list and select the Find-Me print queue. Examine the settings to ensure that all of the appropriate “destination queues” have been selected.
Second, check the Devices section of PaperCut to ensure the MFD/Copier has “Enable find me printing support” enabled, and that the correct “destination queue” is selected that will output to this printer. If the wrong queue is selected, the print job may be going to the wrong printer, so it’s important to confirm this setting.
It’s possible to configure Find-Me printing so that jobs can be submitted to one server, and then released to a queue hosted on a completely different print server. We call this “Cross server redirection” and there are a few ways this can go awry.
- Both servers must be the same OS type (Windows → Windows, or macOS → macOS etc). If you have a mixed environment of Windows, Linux, and macOS servers and clients then take a look at Find-Me Printing on Multiple OSes to see what’s required.
- Make sure that the PaperCut Print Provider service is running as a Service Account that has rights to submit a job to the destination print queue. Local system will not have these permissions.
- Confirm the Print Provider service on both servers is actually running (we’ve seen cases where the password for the service account on one server expires).
- In Windows environments, “Share this printer” must be enabled for the destination queues on the Secondary Server for cross-server redirection to work.
If so, you may want to read about this extremely specific, perfect-storm condition that happens when customers set up Find-Me Printing and use the built-in authentication methods available in some manufacturer’s print drivers.
The telltale sign is that one print job will be stuck in the Windows print queue with the status “Paused - Spooling” and another will have the status of “Printing”, and seems to hold up all other print jobs.
Check the Windows print queue on the server by opening printmanagement.msc → right-click on the printer in question → click Open Printer Queue. If you see jobs held up like this, then head over to our article Print Jobs stuck with the status of “Printing”.
To check for this error, look in the PaperCut Application Log for the message the specified datatype is invalid. If this error is occurring, it will be seen in the Application Log (found in Logs → Application Log).
Here’s the full message:
Unable to redirect job from \\PrintSRV01\find-me-printer to \\PrintSRV01\library-color. Is the "Print Provider" service running under a user account with permissions to redirect to the destination printer? User: Alan-One- The specified datatype is invalid. (Error: 1804) This means that the job couldn’t be redirected from one print queue to another because the way the print job was spooled, called the “datatype”, is incompatible with the way that the print queue is configured.
The most common way this happens is when Advanced Printing Features is enabled on the Find-Me queue, causing Windows to spool the print job in the EMF (Enhanced Metadata Format) datatype, but is not enabled on the destination print queue. For Find-Me printing to work, PaperCut copies the spool files from the Find-Me queue to the destination print queue but if this is expecting a different datatype, that’s when this error might occur.
The solution is to make sure that “Advanced Print Features” is set uniformly across all the print queues in a Find-Me Printing setup (preferably set to disabled).
