Limitations
Since the program rely on other applications to create the print jobs, it only supports file formats where the printing programs behave well. This may cause stability issues if you run this program in a server process. Some printing programs do not handle sessions without user interaction. This means that running the job from a server process can be a bit tricky. My recommendation is that you test the usage with types of documents that you wish to print.
