How to mark a print job as completed in universal print with virtual printer
With graph API, I am able to register a virtual printer in universal print. When a job is submitted it is marked as paused. I am able to download the pdf attached to the print job and set the task to completed. After task is completed, the job gets a new status as pending.
I am not able to figure out how to mark the job as completed after downloading it. I do not want to print the job in real. Only thing we want is to download and save the pdf and mark the job as completed.

If you are developing a virtual printer, we recommend you to use IPP APIs as per the IPP INFRA specification. You can find more information on OEM Universal Print Device Development Overview - Universal Print | Microsoft Learn.
IPP APIs are required for multiple reasons. Some key ones are:
- Ensuring you have support for all print options and attributes. IPP APIs are typically more up-to-date compared to Graph APIs when it comes to printer functions. This is because Microsoft is committed to IPP standards from Mopria and PWG.
- Ability to acknowledge the print job - this locks the print job to be printed by the printer which acknowledged the print job.
- Ability to update print job status - this is very important as some client behavior depends on the correct print job state
- Ability to easily integrate with Secure release and Universal Print anywhere (pull print feature coming soon)
Graph APIs are a great fit for:
- Cloud workflows that can be applied on top of a print job queued in cloud (like implementing user quotas, print policies etc.). Check - https://learn.microsoft.com/en-us/graph/universal-print-webhook-notifications?view=graph-rest-beta#create-subscription-printtask-triggered-jobstarted-event
- If your printer is hosted in cloud, then you can use Graph change notifications. These help in notifying about new jobs (ready to be released at printer) instead of IPP notifications.
