In nt te er rf fa ac ce es s
This appendix provides technical information for the parallel and serial interfaces
1
1. . T Th he e P Pa ar ra al ll le el l I In nt te er rf fa ac ce e
The parallel interface of this printer fully supports the Centronics protocol plus the specific features
requested by the EPSON and IBM printer connection in monodirectional mode and the Compatibility
and Nibbles modes in bidirectional mode, plus the negotiation phases and the device identifier (as IEEE
P1284).
The parallel interface is available on a specific 36 contact connector type AMPHENOL
57-40360-12-D56 or equivalent connector for 1284 Type B.
•Drive Capability
Up to 15 feet (5 m) on AWG26 min. wire size of twisted conductors on TTL receiver. The max.
reachable distance is conditioned by the host drive capability and by the noise level along the
interface cable path.
•Printer Connector Type
36 pins, 1284 Type B
•Cable Connector
25 pin, 1284 A Type
S
Si ig gn na al ls s D De es sc cr ri ip pt ti io on n
According to the IEEE - P1284 Standard, the pins assume different meanings and are identified by
different names depending on the actual handshaking mode as follows:
•Compatibility mode (Centronics)
This is the lower level mode provides an asynchronous, byte-wide forward (host-to-peripheral)
channel with data and status lines used according to their original definitions. The interfaces power
up in the compatibility Mode Idle phase.
•Nibble Mode
This mode provides an asynchronous, reverse (peripheral-to-host) channel, under control of the
host. In this mode, peripheral device to host data bytes are sent as two sequential, four-bit nibbles
using the four peripheral-to-host status lines. These two modes cannot be active simultaneously.
•Byte Mode
This mode provides an asynchronous, byte-wide reverse (peripheral-to host) channel based on
eight data lines of the interface for data and the control/status lines for handshaking. Byte mode is
under host control and it cannot be simultaneously active with compatibility mode.

O
Op pe er ra at ti in ng g P Ph ha as se es s
The link protocol is mainly based on the following three phases:
•Negotiation Phase
This phase is activated always by the host, only when in compatibility mode, and defines:
- whether a bidirectional link protocol can be established.
- the handshaking mode as well as the communications mode to be used.
- the device identification, if supported.
•Communication Phase
This phase is based on well defined handshaking rules which depend upon the selected link mode.
•Termination Phase
This phase is initiated by the host and returns the interface to the compatibility mode.

Description of the signals in monodirectional link:
Signal Name Pin N° Source Description
STROBE 1 HOST Clock signal which controls data transmission with its falling edge.
ACK 10 PRINTER Negative pulsed signal indicating that the printer has received data and
is ready to accept the next set of data. Also sent when the printer is
switched from off-line to on-line and at the end of the initialization
time. The BUSY line is always active.

PRINTER /
HOST
Data 8 is the most significant bit. These are the data lines used by host
to transfer control code or ASCII codes.
DATA BIT 8 9
BUSY 11 PRINTER When high, this signal indicates that the printer cannot accept data
or control codes. This signal goes high during data processing, in
test and program modes, during initialization, when the buffer is
full, and when a paper jam, paper end or paper size error occurs, in
case of a power-on reset, the reception of a STROBE signal, while
the register was not yet read, or when the INIT line is still active.
