Unfortunately, we have no information about any particular tsf to pdf document conversion, or even TSF format that would be used for documents.
Perhaps the searches are related to a tool known as Strater that uses .tsf files for templates, but these are just settings and presets for actual labels. If you want to print the designs, look for the .sdg files. In this case Strater exports to the visualization to image that is then exported as PDF, making it a considerably large file.
But any document or graphics content can be exported to PDF format simply by using the print function and virtual PDF printer.
