Whilst most information relates to Windows 10, it appears that a number of recent updates have adversely affected the printing sub-system â it manifests itself with random print job failures, job not reaching the queue, or disappearing from the print queue immediately after appearing but not reaching the printer, and reporting of GDI+ errors. Problems are across Type 3 and Type 4 drivers, with Type 4 being seen to more prone to jobs not reaching the queue.
It seems that versions of the updates have been rolled out to other supported OS. Some of the issues are detailed here

Application of the latest Cumulative update for Windows 10 or KB5000842 appears to fix the issue.
Obviously if running a production system on a server OS you will have had significant control over update application, but for a customers choosing to run Formate on a Windows 10 machine in production, the problem updates may have been applied automatically, thus introducing the issues, so please be aware.
