Interface data external Centronics interface
With the parameter ’centronics’ of the interface menu the Centronics interface
can be set to the ECP mode (centronics=ECP) or not (centronics=printer).
If the parameter ’centronics’ is set to ’printer’ the Centronics interface can only
be work in the compatibility mode.
The parameter ’centronics’ also controls how to set the signal ’PError’ from the
printer (see section “Cable connection“ and “Signal description printer side in the
compatibility mode and ECP-mode“ of the Centronics interface).
Centronics modes
Compatibility mode and ECP mode correspond to the norm IEEE P1284 D2.
Type of connector
The interface of the document printer have a 25-pin D-SUB plug at the host side and
a
36-pin Centronics plug at the printer side.
