I had to use a scheduled script to print invoice PDFs sequentially, meaning using the NS queue. So I can't deliver on concatenating every PDF to a pdfset to display in the browser (not easily). We're using Adobe DC, which can't even print multiple PDFs. It's easy with pdftk, commandline or otherwise, so I'd like to make a script to run a simple pdftk command in windows. I'd rather not mess with forking a process in C if possible. Should I look at powershell scripting? Another language?
