The following options are used when the parallel interface is selected.
I-Prime: Buffer print—when this signal is received, the printer is initialised after the
buffer data is printed. Buffer clear—the printer is initialised after the current line has
been printed. Invalid—This signal is ignored.
Pin 18: This pin supplies 5V or open circuit as required by external device when
connected to interface.
Auto Feed XT(Epson emulation only): There is normally no Line Feed after a
Carriage Return if the Auto Line Feed is set to NO. However, in the Epson emulation,
if the Auto Line Feed is set to NO and the Auto Feed XT is set to valid, a Line Feed
is executed upon an Auto Feed signal on pin 14 of the parallel interface. This exception
may be necessary for some hardware/software combinations.
The following options are used only if the serial interface is selected (see Appendix
C for details).
Parity: Selects parity.
Serial Data 7- or 8- Bits: Selects data format. When the Serial Data 7- or 8- Bits is
set to 7, the Parity must be set to either ODD or EVEN. 7- Bit Serial Data will not be
printed correctly if the Parity is set to NONE.
Protocol: Selects interface protocol.
Diagnostic Test: Activates the printer's interface diagnostic test.
Busy Line: Selects line used for busy signal.
Baud Rate: Selects data transmission speed.
