INTRODUCTION
DP24-40 H 4
GENERAL FEATURES
The DP24-40 H is a practical, user-friendly desk printer.
It is, therefore, the ideal solution for applications which require the immediate
printing of data on a ticket, whether they be of an industrial, professional or
laboratory nature. Typical fields of application are: POS, weighing systems,
receipts (not for tax purposes) as well as for security, controlling and
diagnostics purposes.
It is equipped with a rapid, 8-needle impact print mechanism and uses 57.5
mm paper rolls.
The DP24-40 H printer is distinguished by the fact that it has an internal
power supply and is extremely compact.
It has an RS232 serial interface and a 1Kbyte reception buffer. It can also be
equipped with a Real Time Clock.
DESCRIPTION OF THE PRINTER
The DP24-40 H printer (fig.2) has an ABS casing (1) with a front cover (2)
which opens to allow access to the paper roll and print head.
The control panel is located on the front (3) and has a PRINT key, a FEED
key and a LED to indicate Power.
(Fig.2)

INTRODUCTION
DP24-40 H5
•ON/OFF key. When pressed, it switches the printer on (fig.3) and when
released it switches it off.
•PRINT key. When pressed, it causes the transmission, in serial, of the
control character “$0D”, if this has been enabled at the printer setup
stage.
•FEED key. When this is pressed the paper feeds forward manually. If
this key is pressed briefly, when the RTCK option is installed, the date
and time of day is printed.
•When the green POWER LED lights up, this indicates that the printer is
working properly.
(Fig.3)

1. INSTALLATION AND USE
DP24-40 H11-
1.1 CONNECTIONS
1.1.1 Power supply
The DP24-40 H printer has a feed cable 1.5 m long with a standard plug.
WARNING:
ensure that the mains voltage is compatible with the
characteristics of the equipment.
1.1.2 Logic circuitry
The DP24-40 H has an RS232 serial interface with a 9-pin female connector.
For the arrangement of the signals on the connector pins and for hooking up
to the PC, please refer to the following table:

1.1.3 Cash-drawer connector
The impulse specified by the command ESC p is an output signal to the
cash drawer connector. The host can acknowledge the status of the input
signals through the commands DLE EOT, ESC u, GS r.
The functions of the cash drawer connector pins are described in the
following table:

1.2 CONFIGURATION
The DP24-40 H enables the configuration of the printer default parameters.
The parameters affected during configuration are:
(Tab.1.2)
Cash drawer extraction enabling signal
Current: 1A (max 10 sec.) or less
Output wave form: t1 (ON time) and t2 (OFF time) are
specified by ESC p.
In the ON time (t1) phase, the output voltage is
approx. 0V.
In the OFF time (t2) phase, there is a high
impedance output voltage.
The solenoid valve must be connected
from Pin 2 to Pin 4 of the cash drawer
connector.
WARNING:
to avoid current overloads, the resistence
of the cash drawer extraction solenoid
must be at least 24 Ω.Cash drawer
connector Solenoid
(Fig.1.2)

1. INSTALLATION AND USE
DP24-40 H31-
• Emulation type (custom, EPSON, CITIZEN)
• Print direction (normal or reverse)
• Selection of the character dimensions (small, double width, double
height, expanded)
• Character set
• Enabling of the CR command
• Baudrate selection
• Protocol selection
• Flow control selection
• Enabling of transmission of CR command when the PRINT key is
pressed
• Selection of reception buffer (1KB / number of columns)
• Enabling of Real Time Clock (optional)
• Enabling of seconds on Real Time Clock (optional)
The settings made are saved on the EEPROM (non volatile memory).
Normally configuration through the keypad is enabled. To disable it,
shortcircuit jumper JP3 on the printed circuit board.
If when the printer is switched on, both keys are held down, the printer enters
configuration mode and prints the first modifiable parameter. After this, each
time the PRINT key is pressed, the parameter is modified and its current
value is printed. Once the required value has been obtained, press the
FEED key to proceed to the next parameter, and so on. Once all the
parameters have been run through, the printing of a message signals the
end of the setting procedure.
1.3 AUTOTEST
To run the autotest, hold down the FEED key, while switching on the printer.
The autotest causes the printing of the printer’s current setting data and the
printing of the complete ASCII character set.
1.3.1 Hexadecimal dump
After completing the autotest procedure, the printer enters Hexadecimal
Dump mode. This function is used for the diagnostics of characters received
in serial. In fact, these are printed in hexadecimal code together with the
corresponding Ascii code.

DP24-40 H 41-
.4 PRECAUTIONS
WARNING:
1) Before connecting the printer to the mains, ensure that the power
supply or system ON/OFF switch is in the OFF position.
2) Do not print without paper or ink ribbon;this leads to rapid deterioration
of the needles.
3) Do not pull the printer carriage manually.
4) Do not put foreign objects inside the cutter.
1.5 MAINTENANCE
1.5.1 Changing the paper roll
To change the paper roll, proceed as follows:
1) Open the upper cover and position the paper roll so that it rotates in the
right direction, as shown in the figure;
2) Insert the end of the roll in the slit of the print mechanism;
3) Press the FEED key; a few centimetres of paper automatically feed out
of the printer;
4) Tear off the paper and re-close the cover.
(Fig.1.3)

1. INSTALLATION AND USE
DP24-40 H51-
WARNING
Before inserting the paper, ensure
that it is cut evenly
1.5.2 Replacing the ink ribbon
To replace the ink ribbon, proceed as follows:
1) Open the door and remove the used cartridge by pressing at the point
marked PUSH (1), as shown in the figure;
2) Fit the new ribbon, ensuring that it is correctly positioned;
3) Tighten the ribbon by rotating the knurled knob (2) in the direction
indicated by the arrow; then re-close the door.
1.5.3 Paper jam
1) To remove the paper from the print mechanism, pull it upwards;
2) If the paper comes out the front, obstructing the printing area, first tear off
the excess paper then carefully remove the scrap which has jammed.
