Specifications
A-7
Handshaking: Refer to the IEEE-1284 specification
Signal level: IEEE-1284 Level 1 device
Data transmission timing: Refer to the IEEE-1284 specification
Serial interface
The printer’s built-in serial interface is based on the RS-423
standard. This interface has the following characteristics:
Standard: Based on RS-423
Synchronization: Synchronous
Bit rate: Approx. 900 Kbps
Handshaking: X-ON/X-OFF DTR protocol
Word format:
Data bit: 8 bits
Parity bit: None
Start bit: 1 bit
Stop bit: 1 bit
Connector: 8-pin mini-circular connector
Recommended cable: Apple System Peripheral-8 cable (Part
number M0197)
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,
the input and print buffers are cleared, and all settings return to their
default values. However, the printer mechanism is not initialized if
the printer is turned on within 10 seconds after being turned off. In
this case, the printer caps the print head, and ejects any paper in the
paper path.
Software
initialization
Software initialization clears the print buffer and returns all settings
to their default values, as shown below.
Hardware
initialization
The printer is turned on.
The printer receives an
INIT
signal from the parallel
interface.
Software
initialization
Software sends the ESC @ (initialize the printer) command.
The last panel settings are kept.
