### Printing to Screen
The UEFI standard supports multiple interfaces for printing to the screen. The most simple one is the _Simple Text Output_ protocol, which provides a console-like output interface.

All of these functions are directly provided by the UEFI firmware, the `uefi` crate just provides some abstractions for this. By looking at the source code of the `uefi` crate, we see that the [`SystemTable`][system-table-src] is just a pointer to a [`SystemTableImpl`] struct, which is created by the UEFI firmware in a standardized format (see section _4.3_ of the UEFI specification ([PDF][uefi-pdf])).

The methods of the `Output` type are just [small wrappers] around these function pointers, so all of the functionality is implemented directly in the UEFI firmware.
