The function calls are case-sensitive.`window = system.gui.getparentwindow(event)` should be `window = system.gui.getParentWindow(event)`You can see more about that function [here](http://www.inductiveautomation.com/support/usermanuals/ignition/system_gui_getparentwindow.htm).

The best way to do that is to set up a Client Event Script based on a Tag Change to call that function. For that to work, you need to have a client open when the tag changes. In addition to that, each client will run this script and print out a copy of the screen. The best way to get around that is to use the System Tags (IPaddress or HostName) to determine who prints the screen.
