Print Jobs are showing in the EQPrintQueueViewer but when you login at the embedded device no documents are showing in the Follow-You. Tested WebRelease with the same issue even though if the user login to webtools he sees his secure jobs.
The "Enable multi-server Follow-You" feature is not enabled.
Enable the "Enable multi-server Follow-You" feature under System Manager > Configuration > DRE/DRC and Follow-You Printing, then force DRE cache update
A print job stored in the EQSpool has a cost value of $0.00
In Print Queue Viewer, check the oldest job queued by the user who cannot see any jobs on the embedded. If the oldest job shows a cost of $0.00, delete it from the queue and refresh the cache on the DRE.
