need to print labels from a ecommerce website

Im a wiz with php but i have a challenging client- who wants sandwich labels printed automatically as they are ordered from their website开发者_如何学Python.

what is the best solution for this- the e-commerce website is a php/mysql website i can do a call to some sort of service running but i have no idea how to print the info? what hardware is required.. and where to go for info. I'm sure it can be in some sort of .net app as the printer will connected to a windows machine.

you can create a programed task in windows every minute or every 30 sec that execute a php (php c:/dir/myphpcron.php) wich check out if there is a new order an then generate a pdf and then execute with exec() this:
