With this setting, the printer uses the GeBE-Ir protocol
for communication. The protocol can be used either
through the RS232 or the TTL interface.
Due to the CRC guarded transmission blocks, a secure
data connection can be achieved.

Interfaces • Infrared Interfaces
GeBE E + F GmbH • www.GeBE.net • GeBE Dok.Nr.: SMAN-E-549-V1.1 Thermodrucker GPT-4389
The following protocols can be used:
• IrDA: IR LPT (printer service)
IR COMM 9 wire (optional)
Also see: www.irda.org
• GeBE-IR: simple,error-proof, bidirec-
tional dot to dot IR protocol.
GeBE-Doc.No. MAN-E-395
All standard versions of the printer have the hardware
for an IR transmitter/receiver installed, so the protocols
GeBE-IR and IrDA are available for all standard printers
of the series GPT-4389.
The internal IR tranceiver is installed directly below the
red foil window (10). It is important to consider that inf-
rared transmission will only work "line of sight". The ra-
diation angle is about ±15 degrees. The transfer distan-
ce to "IrDA standard power" devices is 0.6 meters.
Optionally, the transfer distance can be increased to up
to 3 meters by using an additional booster IR-LED.
The printer will signal IR communication through the
LED that is located below the Ir window.
Use of the Sleep Mode
In the setting "IrDA "or "GeBE IR", the IR receiver will
even stay active during sleep mode, so the device will
not have to be swiched on explicitly for printing. The
power consumption of the printer is only about 25µA in
this mode. However, the printer should still be turned
off during long periods of inactivity.
GeBE -IR Protocol
The GeBE-IR protocol is a simple, error protected infra-
red protocol. Data transmission is processed in CRC
protected blocks. With each transmission confirmation,
the printer status is sent back to the host.
The implementation is very easy to realize.
The protocol is disclosed.
IrDA Protocol
5.2 Infrared Interfaces
The printer works with the protocol service IrLPT. In this
service, the printer will not send back any messages.
A bidirectional service "IrCOMM 9 wire" is available on
request.
In the menu setting, the selected baud rate represents
the maximum baud rate. If 57,600 baud is selected, for
example, the printer will start to communicate with
9,600 baud and then switch up to 57,600 or 38,400
baud, depending on the transmitter.
The maximum baud rate of 115,200 should only be re-
duced, if transmission errors occur.
When an infrared transmission is interrupted, the printer
will look for the transmitting master device for about 20
seconds in order to complete the transmission. After
that, the stack is reset, and new inquiries are answered.

Option 2: USB2 Serial Port emulation:
The GPT-4389-USB meets the USB specification V1.1
for full-speed devices. The printer is compatible with
USB V2.0 bus systems.
The USB device class is equivalent to a "Vendor Speci-
fic Device". Therefore, transmission can be done with
virtual COM port drivers. The printer will operate like a
serial printer. The virtual COM port drivers are available
for the operating systems Windows® 98/98SE/ME/
2000, and XP. Consequently, standard GeBE printer dri-
vers can be used.
You can find Windows®and USB drivers on our Inter-
net page. Please read the included installation instructi-
ons. Before initial operation, the matching virtual COM
port driver (VCP driver) and the printer driver have to
be installed.
Setting the VCP Driver
The example shows the setting with Windows® 2000.
The procedure is very similar with XP or Windows® 98.
Starting with the Windows® "START" button, select
"Settings" -> "System Control" and click on the "Sys-
tem" folder.
Select the "Hardware" tab, and click on "Device Mana-
ger".
There, activate the "+" symbol under "Connections
(COM and LPT)", and look for the entry "USB Serial
Port (COMx)".
Open it and click on "Port Settings", in order to have
the settings of the virtual COM port displayed.
It is recommended to use the settings of the virtual
COM port according to the settings of the printer:
115,200; n; 8; 1; XON/XOFF.
If the printer is not operated in step mode, "Hardware
Flow Control" is recommended.
Click on "Advanced" to see the extended settings.
Please make sure that the settings shown below have
been carried out

Never activate an action in the printer driver at the
end of a job. This can cause a loss of data.
Option 1: USB1 printer class:
The USB device class is "Printer Class".
When plugged in, the PC will report "USB printer sup-
port" and install a "USB001"USB port.
Either the standard printer driver of the "system78" or
the port monitor can be used. During installation of the
printer driver, it can be easily guided onto the USB port.
Windows® XP and Windows® CE handle
the numeration of a printer differently. The-
refore, the printer must be conficurated to
the operating system before delivery.

Changing the Paper

GeBE E + F GmbH • www.GeBE.net • GeBE Dok.Nr.: SMAN-E-549-V1.1 Thermodrucker GPT-4389
Inserting the paper roll:
1. Release the printer cover with the green latch.
2. Open the printer cover.
3. Unwind about 10 cm of paper from the roll.
Insert the paper roll in the paper compartment, so the outside
shows toward the printer mechanism.
4. Close the cover by applying strong pressure. You will hear it snap
shut. Now you can rip off paper at the tear bar without the cover
opening up or the paper sliding through the print head.
Which Thermal Paper is Suitable?
The printer is specified for a paper width of 56.0 ±0.5 mm, 75 mm dia-
meter, 60 g/m2paper thickness. GeBE is offering suitable paper rolls
GPR-T01-056-075-025-060A (quality: 5 years) as part of the standard
program. Other papers may cause failures.
Other Types of Paper Available from GeBE:
High Temperature Paper
begins to blacken at about 100°C (standard: app. 70 °C), making it
ideal for applications like parking receipts.
Two-Ply Paper
produces a copy of the first layer with a second layer.
Optionally, the first layer can be rewound.
Adhesive Labels
are connected to each other through perforation. A mark for correct
positioning is located beween the labels. This is the only kind of label
that can be used with the GPT-4389.
Archivally Safe Paper
is a paper that maintains printed images for at least 15 and up to 99
years, if stored in a dark and dry environment.
Two-Color Paper
prints red with the normal setting, black with a higher temperature set-
ting. The temperature can be set by command.

The closed printer is protected against static discharges in ac-
cordance with the EMV guidelines. Since the user may come in
contact with parts that are electrically sensitive, when the printer
is open (like the print head during cleaning, or the electronics
during a battery exchange), the user should make sure that all
possible static charges are discharged through sufficient groun-
ding of the body before touching the printer (e.g. by touching
grounded objects like radiators), in order to safely avoid damage
to the printer.
Which side of the thermal paper can be printed
on?
Usually, the printable side is the one on the outsi-
de of the paper roll.

8 Button Functions • Menu Guide
Description of the Button Functions
The buttons have different functions depending on the status – normal operation or print settings menu.
The time for which the buttons are held down also determines functionality.
FEED / ENTER Button (3)
With this button, the paper can be transported forward. When the feed button is pressed, the printer will first feed
one line of the set font. If the button is held down for more than two seconds, it will feed continuously.
Self Test :
By starting a self test printout, the printer functions can be tested. For this purpose, the FEED button (5) has to
be held down for at least three seconds, when it is pressed to reactivate the printer from power-OFF. The interfa-
ces are not tested. Software version and character set are printed out. For OEM, special printouts can also be
activated during the self test.
OFF / NEXT Button (3) Optional only with second button
On request, this button function can be configured through the "Feed Button"
or installed as an extra button in the housing.
By holding down the OFF/NEXT button for more than three seconds during operation, the processing of batch
file T2 is initiated. In the µ-P-GPT-4389, the command for power-off (after one second) is filed in batch file T2.
This way, the button is programmed as OFF button for the printer (controller with power-off mode).

The most important printer settings can be easily changed with a few strokes using the OPD Menu®(OnPaper-
Display).
They are accessable at any time and can be quickly comprehended with the menu printout.
The inconvenient use of DIP switches and programming through a terminal program are no longer necessary.
The OPD Menu®is operated with only two buttons (OFF/NEXT and FEED/ENTER)
The OPD Menu®is an editor of the initialization batch file "TINIT". See chapter on batch files.

10 Status Messages through LEDs
LED "STATUS" (green) (6)
The STATUS LED flashes in very short intervals, if everything is okay. When an error occurs, it will flash slowly.
Status Messages of the Printer through the Interfaces
Besides the optical status messages through the LEDs on the control panel of the printer, messages are also
transmitted through the serial interface. Most of the time, they are sent as single ASCII characters that can be
analysed by the host.
The following table shows all the status messages.

GeBE E + F GmbH • www.GeBE.net • GeBE Dok.Nr.: SMAN-E-549-V1.1 Thermodrucker GPT-4389
Almost all commands that the printer can receive
through the interfaces and then perform can be ente-
red in the batch files. When a batch file is processed,
the commands it contains are added to the data
stream of the print program sequentially, as if they
were coming through the interface from outside. This
way, all settings that can be done by command can be
processed via batch file. Besides settings commands,
batch files can also contain text and graphics.
The file structure consists of one TMenu and a TINIT,
which are both processed with each system boot-up,
as well as 10 files that can be used freely and can be
retrieved by command. Some of these files can be
addressed through additional events. If the controller
has an EEPROM, it contains a file structure that is
identical to that of the program memory (GPT-4389).
When a file is retrieved, the printer will check, if it con-
tains data in the EEPROM. If not, the file will be pro-
cessed in the GPT-4389. This allows GPT-4389 files to
be over-written.
GPT-4389 files can only be changed at the factory.
The following batch files are accessible:
Factory Settings Allocated in the GPT-4389 Memo-
ry:
• "TINIT" settings after hardware RESET
• "T0 " self test through FEED button after reset
• "T1 " form feed through NEXT button <1 sec.
• "T2 " power-off through OFF button >3 sec.
• "T3 - T9": unused
Text or Graphics, Batch Files in the EEPROM
For the printing of text and graphics, the GPT-4389
has an 8 KB EEPROM (app. 6 KB can be used for lo-
gos).
It is recommended to store logos PCL compressed.
By using the Windows® driver, compression rates of
app. 3 - 4:1 can be achieved.
For comparison: Uncompressed full graphics of 5 cm
length take up 20 KB, or app. 5.7 KB compressed.
Configuration of the Printer with TMenu and TINIT
After a hardware RESET (connecting the power
supply), the printer will check for a described TMenu
and/or TINIT in the EEPROM. If the search is success-
ful, it will process the commands in these batch files,
and will then be ready for operation. If not, the TMenu
and/or the TINIT will be processed in the GPT-4389
with the factory settings.
TMenu:
The OPD-Menue®is a printer function that allows the
user to edit the TMenu in the EEPROM. The TMenu can
only be changed through this menu .
Structure of the TMenu:
<ESC>Y<18h> {density}
<ESC>[<DEZ64><DEZ48> {power consumption}
<ESC>]<DEZ115><DEZ40 {baud rate, settings}
<ESC>e<DEZ5><DEZ2> {power-down time}
<ESC>P1 {font}
<ESC>D0 {text orientation}
<ESC>W0<ESC>H0 {text size}
<ESC>S0 {text spacing}
<ESC>h48 {print width}
TINIT:
The TINIT is always processed subsequent to the TMe-
nu. In the TINIT, other presets that were not incorporated
in the menu can be executed. It also allows settings to
be blocked in the menu by repeating them here.
The following TINIT file is an example of a file that can
be modified by the user. It is available for downloading
from the Internet at the
URL: www.oem-printer.com/GPT-4389
The file will erase the TINIT while printing out all actions
in italics at the same time. Any commands can be ente-
red in the TINIT.

15 Troubleshooting and Recovery
Not every failure means that there is an error that cannot be cleared by the user himself. You will save time and
money by recognizing and fixing simple errors on your own. The following tips are meant to help you with this:
Hardware RESET: Unplug and then reconnect power supply.
Hexdump mode: Triggered by holding down the FEED button for more than three seconds after plugging the prin-
ter in, if no paper is inserted. After the paper has been inserted, the printer will print the data it received as hex
numbers with the appropriate ASCII code without interpreting the data. This will make obvious, which information
the printer "reads" from the incoming data.
In order to leave the HEXdump mode, the FEED button has to be held down for at least three seconds, while the
paper is removed. After leaving the HEXdump mode, the printer is re-initialized by processing the TINIT.
Symptom
Possible Cause
Remedy
Power Supply
The printer seems to be
printing. Paper is transpor-
ted, but not blackened.
Paper:
Wrong side facing the print head.
Only one side of the paper can be prin-
ted on.
Insert paper correctly. The thermosensitive side should
be turned to the outside of the roll (most of the time).
Try the finger nail test: Drag the tip of a finger nail
across the paper, pressing down. The friction heat cau-
ses the thermosensitive side to blacken.
Printer cannot be activated
by pressing the FEED but-
ton.
At the beginning of printing,
the LED goes out just
briefly.
The printer only prints a few
dots in one line.
The paper feed workst, but
the self test does not.
No power.
The power supply is not optimal.
Cross section of feed line too weak.
Supplied power too low.
Check power supply.
Use short feed lines with sufficient thickness.
Check all connections for possible transfer resistances.
Since high peak currents occur with thermal printers,
even the smallest transfer resistances can result in into-
lerable voltage drops. In this case, no power supply
would be strong enough.
The printer only prints a few
characters in one line. If
more is entered, it stops
printing altogether.
Serial Interface
After a few characters, the
printout starts to be incom-
plete.
The printer prints the wrong
characters.
The printer buffer is "over-run" (256
bytes), causing a loss of data. The print
data transmitter shows no reaction to
handshake.
interface problem. The transmission is
faulty. (characters of the upper area are
printed).
Use or check handshake. (software: Xon/Xoff or hard-
ware: CTS).
If necessary: slow down transmission speed, e.g. down
to 1,200 baud.
Use correct interface level. (RS232, TTL?).
The transmission cable may be too long.
IrDA
Wrong data format is set. (the "?" is
printed often).
Bad ground connection that causes a
part of the printing current through the
interface cable. This leads to an in-
crease in potential there, which results
in data corruption.
Set the correct baud rate through the menu.
Check data format.
Check and improve ground connection. Feed current
through short, thick lines.
Host sends a break signal after print job
(only "?" are printed).
Turn off "framing error ".
The printer prints extremely
slowly, when high baud ra-
ted are set.
USB2
The printout stops after a
short time or is repeated
constantly.
Host ignores turn-around time specified
by the printer.
Set lower baud rate.
Wrong COM port settings, or "job end"
action activated in Windows® driver.
Set virtual COM port according to installation instructi-
ons. Deactivate "job end" action in Windows® driver.
