Do you just want background automation of your process - meaning using Simulate Click and minimized window of Outlook or let’s say fully background - via API maybe?
For the second option there is no Print activity for now I think mostly because it depends a lot on the document type that you want to print - from what I’ve understood while reading some articles related to this.
For reference:
c# - Which Windows Print API to call from .net program - Stack Overflow - “Er, those are fancy doc types!! It sounds like you are looking for Windows API functions that can print Word and Excel documents. Is that right? Anyway, no such functions exist. You need Word and Excel. Or a 3rd party library like Aspose. No 3rd party library will do the job as well as the original app though” - this is what some users say.
So I think you can achieve the fully background automation but it would need much more research and testing than what I did.
My suggestion would be to make use of the background automation we currently have (with Simulate option).
