SATO GL408/412E Which interpret the 8th data bit line as a PI signal, Option, Codes, Computer

		Unit 4: Printer Configuration
		CENTRONICS INTERFACE MODE (TABLE 4-6)
MENU		DESCRIPTION
	Is typically for a line-printer and should not normally be enabled. Is used for legacy applications
	which interpret the 8th data bit line as a PI signal.
	•	Enable - factory default. The PI line is not passed directly from the host to printer; all 8 bits
Data Bit 8
		are used for data bits. Characters in the Hex 80 to FF range can be accessed.
Enable*
	•	Disable - when the PI line is enabled, data bit 8 internsionally indicates PI line status. To use
		the PI line, disable data bit 8 and enable the Host PI configuartion option (under PI Ignored
		option.
	Paper Instruction Ignored. This signal is used to control vertical paper motion.
	•	Enable - factory default. Ignores the PI signal and treats the data as characters or control
PI Ignored
		codes.
Enable*
	•	Disable - causes the printer to interpret the eight data lines as VFU commands when the PI
		signal is true.
	This parameter must be set to match the response polarity of the host computer.
	•	Standard - factory default. Does not expect the host computer to invert data.
Data Polarity
Standard*	•	Inverted - expects the data received on the data lines from the host computer to be inverted.
		One become zeros and vice versa.
	Response Polarity. This parameter must be set to match the response polarity of the host
	computer.
Resp. Polarity
	•	Standard - factory default. Does not invert the response to the host computer.
Standard*
	•	Inverted - inverts the response signal sent to the host computer.
	The strobe signal tells the printer when to look for data on the data lines. The printer can either be
	set to assert a busy signal after each data byte or after the printer’s buffer has filled.
Busy on Strobe
	•	Enable - factory default. Asserts a busy signal after each character is received.
Enable*
	•	Disable - asserts a busy signal only when the print buffers are full.
	Specifies whether the data is read on the leading or trailing edge of the data strobe signal.
	The options are Leading and Trailing. Leading is the factory default.
Latch Data On
Leading*
	Is a normally low signal on the parallel port. When initiated, it is designed to reset the parallel port
	and clear the printer buffer.
Prime Signal
	•	Disable - factory default. No action when the signal is initiated by the host.
Disable*
	•	Enable - reboots interface and clears the printer buffer when the signal is asserted.
	Top-Of-Form Action. When enabled, the printer will feed out the job in process when the prime
	signal is activated through the Centronics interface. If disabled, the job in process may be
TOF Action
	aborted.
Reset*
	Regardless of this menu, the prime signal will also reset the printer.
	This menu configures the amount of memory allocated for the serial port buffer. The range is 1 to
	16 Kbytes in 1 kbyte increments.
Buffer Size in K	Note: If a baud rate 19200 or greater is selected, the Buffer Size in K parameter may need to be
16*
	increased from the default to 16 Kbytes to improve performance.
	The factory default is 16.
