If the printer or restaurant ticket software exposes an API that is friendly to send data for printing, then you should be good to go in theory. You may want to look a little further on to which machine houses the web service and its availability.
If it goes down because it was installed on some random desktop computer, then your entire online ordering system is down. Make sure that service is installed on a reliable machine.
If you had the service centrally hosted then you would not have to worry about the stability or security around the service as much, and then have your online ordering system and the restaurant both ping that centralized service for outstanding
orders to print.
