The shortcut output workflow component, To printer enables you to print out the current printable payload in the workflow onto a selected printer.

Before calling this component you need to make sure:
That the payload of the workflow contains one of the printable formats.
That a printer has previously been selected e.g. with the Set printer component.
An example of how this can be used is found here. The example use a PCL file, but the principle is the same for any other printable formats.
