Serial I/F
CSF Type:
The menu item CSF Type only appears for wide printer
models. If you are working with a wide cut sheet feeder, the value
must be set to Wide. If you are using a narrow cut sheet feeder with
a wide printer, set the value to Narrow.
must be set to Wide. If you are using a narrow cut sheet feeder with
a wide printer, set the value to Narrow.
I-Prime:
the signal on the I-Prime line of the parallel interface can
either be ignored (Invalid), cause printing out of the current buffer
(Buffer Print) or erase the print buffer (Buffer Clear).
(Buffer Print) or erase the print buffer (Buffer Clear).
Pin 18:
pin 18 of the parallel interface can be switched to 5 volts or
open if required.
Auto Feed XT:
In essence, no line feed (LF) is performed after a car-
riage return (CR) if Auto LF is set to No. If, however, in Epson mode
Auto LF

is set to No and Auto Feed XT to Valid, a line feed is per-
formed when an external Auto Feed Signal (Centronics pin 14) is
issued. This special case can be necessary for certain combinations
of hardware and software.

In the case of serial data transmission, the data bits of a byte are sent
one after the other via a line to the printer. For correct transmission,
it may be necessary to change the interface settings so that they
match the settings of your computer. If there is a serial interface
installed and this has been activated in the menu, the menu items
described below appear.

Parity:
Selects the parity. For each byte of data, a start bit with logi-
cal value 1 is transmitted, followed by the 7 or 8 bits of data accord-
ing to the data length defined. If required, a parity bit can follow for
the purpose of data checking.

Serial data 7/8 bits:
Defines the data format. It is necessary to differ-
entiate between the data format (7 or 8 bits) and the transmission
format (data bits plus parity bit set or not set).
format (data bits plus parity bit set or not set).
Protocol:
Selects the interface protocol. There are two protocols that
can determine the sending and receiving of data. In the case of the
Ready/Busy protocol, the DTR, RTS or SSD line indicates the print-
er's readiness to receive by means of the voltage level. In the case of
the X-ON/X-OFF protocol, sending/receiving is controlled (hand-
shake) via special characters transmitted on the data line.
