I'm developing a web application in PHP and we need to print some files/labels from this web application. The web application is hosted on a 3rd party hosting provider. The thermal printers are available in the intranet which can be accessed via Windows SBS 2008.
The windows SBS 2008 can be accessed through a public domai/IP. IIS is currently running on the same server.
Is there any way to print the files from Internet by sending a command to the SBS server, something like API request with authentication?
Please note: I have limited access to the system, so installing any softwares on SBS server is not practical.
