Chapter 1: Overview

The printing paper width of RD-FH8C7 THERMAL PRINTER is 58mm. Equipped with a

cutter, and supports the full cutting or half cutting function. The series printer increases

sheet metal casing on the basis of the W series, which is more convenient to install for

customers. The printer uses fully enclosed large paper warehouse design, which can

effectively prevent rain and dust from entering.

This series take into account unattended printing capabilities, and in order to prevent

inadvertent phenomenon, the paper and key functions are placed inside the printer. Only

when the panel is opened, the printer can change paper and do the button operation.

Meanwhile, also equip with a safety lock on the printer panel, after the lock to the printer's

front panel will not be opened, and at this time only the professional staff with the key can

open the front panel.

The series printers have two models: RD-FH8C7-P and RD- FH8C7-S. The former is a

26-pin standard parallel printer; and the latter is 5-pin RS232 serial interface printer. The

series printer has the printing paper width, high speed, small size and other characteristics.

They are used in the Bank Queue, supermarkets lockers, game consoles, subway

coupons and other equipments.

1.3operating

There is an indication button on the printer’s panel, and this button is not only an indicator

but also a function key.

1.3.1operating key

FEED button: Click the button and the printer feed paper one line. Hold down the button

and the printer continuously feed paper.

1.3.2 Operation

1. self- test

Step 1: The power of the printer is turned off.

Step 2: Press the indicator button

Step 3: Energize the printer for about 2 seconds and the printer will start the self-test.

2. Load paper

Step 1: Open the security lock of the printer, and open the printer’s cover.

Step 2: Pull out the right wrench of the printer, and open the printer's creel.

Step 3: Remove the printer’s paper axis and insert the roll paper. Then put the paper into

the paper storehouse, and get stuck the paper axis, and fasten the printer creel.

Step 4: Pull out the paper end, and fasten the cover. End the loading paper.

3 Paper feed

Under the printer charged state, hold down the buttons, and the printing paper starts

feeding.

1.3.3Indicator light

Power Light:

When the printer is powered, the indicator light is bright with green light for long.

Status Light:

When the printer lacks the paper, the indicator light will be in a state of continuous glint

with green light.

1.4 Appearance size and installation dimensions (Unit:

mm)

Appearance size: feet inches length 135.5 mm * width 136.5 mm * depth 66.5 mm

Installation dimensions: length 127.5 mm * width 128.5 mm

Chapter 2: communication interface

2.1 serial interface

2.1.1Define of Interface

Data transfer: Serial

Synchronization way: Asynchronous

Handshake signals: CTS / RTS, DTR / DSR or XON / XOFF

Baud Rate: 1200,2400,4800,9600,19200,38400,57600,115200 bps. They can be

changed by DIP switch selection.

Data Length: 8Bit Parity: None Stopping bits: 1

Interface: 5pin needle socket

Import(in)

The printer’s dashboard sends

the ‘X-ON/X-OFF’ Handshake

Protocol ，the printer sends

control code ‘X-ON/X-OFF’ to the

computer.)

When the signal is in a state of

‘MARK’, it means that the printer

is busy and can’t receive data.

But when the signal is in a state

of ‘SPACE’, it means that the

printer is ready to receive data.

说明

When the printer is lack of paper, it will stop printing, and online the

indicator light glows green and will be continuous glint to alert the lack

of paper.

OFF

When it is OFF, the printer will not respond for the lack of paper.

2.1.5Data transmission method of serial interface

The receiving buffer of the printer is 16K

(1) When the number of sending data once is less than 16K, the data can be directly sent.

And the sending method is as follows:

(2) If large amounts of data once is sent, need to judge the mark ‘CTS’ when sending the data.

When the mark is ‘1’, the data can’t be sent. When the mark is ‘0’, the data can be sent. Data

can be sent in the form of packets or byte. When the data is sent in the form of packets, each

data packet can’t exceed 256 bytes, and the sending flowchart is as follows:
