Centronics protocol
Centronics uses hardware handshaking. The computer sends a STROBE signal
to move each byte of data into the printer, at which time the printer signals
BUSY. When the transfer is complete, the printer sends ACKNOWLEDGE to
the computer and another cycle can begin.
Serial protocols
Two types of computer-to-printer handshaking, (and their variants), are
available on the Océ 9300 printer:
■
Hardware
■
XON/XOFF
Depending on the emulation selected, handshake protocols can be set either
through the software or the control panel.
When invoking a handshake protocol manually, the printer offers you the
following character transmission handshaking selection:
■
CTS2 for hardware handshaking
■
XON4 for XON/OFF software handshaking
Your host or software documentation should tell you which handshaking is
needed.
■
XON4: The printer sends XON when its buffer has enough memory to
receive character data. It sends an XOFF character to the computer when its
buffer is almost full, indicating that the computer should stop sending
characters.
■
CTS2: Whenever the printer's buffer has enough memory to accept
characters, it activates the CTS signal. It then de-activates the signal when the
buffer is full.
Note:
Hardware handshaking is enabled using the HP-GL ESC.P3 instruction.
Xon/Xoff handshaking is enabled via the software, using the ESC.P1 HP-GL
instruction.
