EPSON Stylus COLOR 200
EPSON Stylus COLOR 200-4 6/96 Ink Jet Printers
Parallel Interface Specifications
Your printer is equipped with an 8-bit parallel interface.
Pin Assignments
Notes:
The column heading “Direction” refers to the direction of signal
flow as viewed from the printer.
“Return pin” denotes the twisted-pair return pin to be connected
at signal ground level. For the interface wiring, be sure to use a
twisted-pair cable for each signal and to complete the connection
on the return side.
All interface conditions are based on TTL level. Both the rise and
fall times of each signal must be less than 0.2 microseconds.
Data transfer must be carried out by observing the ACKNLG
or
BUSY signal. Data transfer to this printer can be carried out only
after receipt of the ACKNLG
signal or when the level of the BUSY
signal is LOW.

These signals represent
information in bits 0 to 7 of
parallel data respectively.
Each signal is at HIGH level
when data is logical 1 and
LOW when it is logical 0.

ACKNLG
OUT
About a 5-
µ
s pulse. LOW
indicates data has been
received and the printer is
ready to accept more data.
11 29 BUSY OUT
A HIGH signal indicates the
printer cannot receive data.
The signal goes HIGH in the
following cases:
1) During data entry
(for each character)
2) During initialization
3) During self test,
demonstration, and
default setting printing
4) During a printer-error
state
12 28 PE OUT
A HIGH signal indicates the
printer is in a paper-out state
or in an error state.

INIT
IN
When this signal goes LOW,
the printer controller is reset
to its default state when the
power is first turned on and
the print buffer is cleared.
This level is normally HIGH;
its pulse width must be more
than 50
µ
s at the receiving
terminal.

OUT
This signal level goes LOW
when the printer:
1) Is out of paper
2) Is in an error state
3) Has no ink cartridge
