Yes, you can use some of the TSPrint binaries to execute actions usually done through TSPrint. For example you can just execute the following command line command:
C:\PROGRAM_FILES\TerminalWorks\TSPrint Server\pdfwriter.exe open "YOUR_FILE"
This would then invoke the same procedure which you is done when you right click on a file and select TSPrint Open Locally.
Besides the open option you can also use:
-send - To send the file to the local workstation. (A file save dialog will appear)
-mail - To send the file as a new e-mail with the file attached to the e-mail.
