PDF print screen in every TS session

Dear experts,

I currently configured an old PDFcreator version (version 1.2.3) on a Windows server 2012 R2 terminal server.
They needed this version for an selfbuild application. a higher version of this application isnt working.

Problem is. : everytime someone prints a document to this pdfcreater. all users are getting a popup. with name of the user in the author field.

how can i isolate this application that only the creator itself gets the message.

Thanks in advance.
