I have a web-based PHP script used for referring patients to an Emergency Department. The script is hosted on a remote server and the hospitals access it via a URL. I need the script to be able to print out info on a referred patient onto the hospital's local network printer. How do I go about adding this functionality to the script? The script is running on a linux server/Apache using PHP and MySQL. Is there a printer class somewhere that I can include in the script? I do not need a code snippet/class that merely makes a page "printer-friendly." I need a class that sends the data directly to the printer for printing without having a pop-up printer window.
