The printer device offers a way of sending configuration-independent
output to a printer attached to the Amiga. It can be thought of as a
filter: it takes standard commands as input and translates them into
commands understood by the printer. The commands sent to the printer are
defined in a specific printer driver program. For each type of printer in
use, a driver (or the driver of a compatible printer) should be present in
the devs:printers directory.
