Initialization
The printer can be initialized (returned to a fixed set of
conditions) in these ways:
Hardware initialization
When the printer is turned on, the printer mechanism is
initialized and the input data buffer and print buffer are
cleared. Printer settings are returned to their default values.
However, the printer mechanism is not initialized if the
printer is turned on within ten seconds after turning it off. In
this case, the printer caps the print head, and ejects any paper
in the paper path.
Software initialization
This clears the print buffer and returns printer settings to their
default values. However, it does not initialize the printer
mechanism or clear the data buffer.
Interface
Your printer is equipped with an 8-bit parallel interface and a
serial interface.
Parallel interface
The built-in parallel interface has the following characteristics:
Forward channel
Data format: 8-bit parallel, IEEE-1284
compatibility mode
Synchronization: STROBE
pulse
Handshake timing: BUSY and ACKNLG
signals
Signal level: TTL compatible
Connector: 57-30360 Amphenol connector or
equivalent
Reverse channel
Transmission mode: IEEE-1284 Nibble mode
Adaptable connector: 57-30360 Amphenol connector or
equivalent
Synchronization: Refer to the IEEE-1284
specification
Handshaking: Refer to the IEEE-1284
