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)
The printer can be initialized (returned to a fixed set of conditions)
in these ways:
Hardware The printer is turned on.
initialization The printer receives an
interface.
Software Software sends the ESC @ (initialize the printer) command.
initialization The last panel settings are kept.
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 clears the print buffer and returns all settings
to their default values, as shown below.
