Having to interact with Word was by the design of the person who set it up. It does not have to be that way.
I use Word Automation. The merging, printing, etc all happen in the background. The user never have to see Word The only see the output at the printer and/or PDF files. Just like printing a report without previewing first. I do allow the user to have the option to interact with Word to be able to preview the completed merge before printing.
