The different printer versions are powered from speci-
fic power sources
• a rechargeable battery pack (Standard NiHM cells)
• Li-ION batteries (rechargeable)
• from a stabilized power supply (5 V, 1.5 A)
• from 4 Mignon (AA) non-rechargeable batteries

The battery pack includes 4 NiMH Mignon (AA) cells.
It also has a temperature sensor to monitor the batte-
ry temperature. A circuit-breaker is integrated to pro-
tect against short circuits.
The battery is connected with a 7 pin connector
through connection (14) on the controller board. This
is done through the window in the battery compart-
ment. The plug-in power supply for charging (8-
28VDC unregulated) is equipped with a connection
cable and a plug that fits socket (12), which is polarity
protected. The plug-in power supply for charging is
part of the supplied set has a connection cable with
the matching connector plug attached. It will supply
the required charging current at about 12V-DC, which
is controlled by the internal charging circuit. This will
recharge the battery in about 4 h. However, if the bat-
tery is over-discharged, a formatting charge with a
low current (<10 mA) is processed first. When the
battery voltage has reached a certain level (after app.
1-5 minutes), the controller will start the charging pro-
cess and turn on the green LED (6).
During the charging process, this LED, which is loca-
ted on the control panel, will signal through different
flashing sequences, whether the fast or the trickle
charge mode is active. With one full battery charge
(1.500 mAh), the printer can print about 50 m of paper
with 15% blackening (normal text). As an option, a
33

dual cell Li-Ion battery can be installed in order to in-
crease the print speed and the life time, and to avoid
the memory effect of the NiMH battery in the long
term.

In an OEM-version the battery compartment has bat-
tery contact springs (16) for Mignon (AA) cells for the
operation with externally charged batteries, or with
non-rechargeable batteries. This printer version does
not include an internal charger. It can be adjusted to
different battery efficiencies by command.
This version is powered either through 4 non-rechar-
geable power batteries or 4 externally charged batte-
ries (Mignon, AA).

Whenever the printer does not have data to process, it
will switch to idle mode. In this mode, it appears to be
100% active and ready to accept data. The power
consumption in this mode is typically 5mA.
SS

If a sleep time has been set via menu, the printer will
switch to the power-down mode after the set time has
passed. Any kind of data transfer (even infrared), acti-
vities on control lines, connecting the charger, or sim-
ply pushing of the FEED/ENTER button will reactivate
the printer immediately without changing its settings.
Only the print buffer will be erased.
The necessary reactivation and waiting for the ready
message of the printer has to be considered in the
printer drivers.

All standard versions of the printer have an IR transmit-
ter/receiver, so the protocols IR-GeBE protocol and
IrDA are available for all printers of the series GPT-
437x.
The printer has an internal IR tranceiver installed di-
rectly below the red foil window (10). Next to it, a red
LED will light up, whenever IR communication is in
operation.
It is important to consider that infrared transmissions
only work "at sight". Between transmitter and receiver,
there may be no shadow casting object. The radiation
angle is about 15 degrees. The transfer distance, which
strongly depends on the efficiency of the opposite side,
is about one meter. It can be expanded to < 3 meters
by installing a booster-IR LED.
While the GeBE-IR protocol and the IrDA protocol act
bidirectionally, the HP-IR protocol only works unidirec-
tionally, i.e. the printer receives print data, but cannot
send any messages (like buffer full) back. The timing of
the data transmission is tuned in a way, that the printer
will always be able to print all data that is sent without
any loss of data.
The following protocols can be realized:

•• IIIIrr rrDD DDAA AA:::: IR LPT (Printer Service)
IR COMM ( Modem Service)

When the settings "IrDA "or "GeBE IR" are selected, the
IR receiver is also active in sleep mode. Therefore, the
device does not have to be turned on explicitly for prin-
ting. The power consumption of the printer is only about
25 ±A in this mode. However, for longer periods of inac-
tivity, the printer should be turned off.
When the setting "HP-IR" is selected, the IR receiver is
turned off during sleep mode. Therefore, the device has
to be turned on explicitly for printing. The power con-
sumption is only about 18 ±A in this mode. However, for
longer periods of inactivity, the printer should be turned
off.

The GPT-437x-FLASH-USB corresponds to the USB
specification V1.1 for full-speed devices. The printer is
compatible to USB V2.0 bus systems. The USB device
class is equivalent to a "Vendor Specific Device". The-
refore, transmission can be done with virtual COM port
drivers. The printer will operate like a serial printer.
The virtual COM port driver is available for the opera-
ting systems Windows 98/98SE/ME/2000 and XP, and
possibly WinCE from the second quarter of 2004. For
Linux V2.40 and up, there is a direct Kernel support.
Therefore, a driver is not required. Standard GeBE prin-
ter drivers can be used.
OO
OOpp ppee eerr rraa aatt ttiiiioo oonn nn
Before the first operation, the matching virtual COM port
driver and the printer driver have to be installed. The
COM settings of the virtual COM port have to be set in
accordance with the printer settings (recommended:
115,200, n, 8, 1, XON/XOFF). If sleep mode is selected
for the printer, it will go into sleep mode after the set
time period.
However, the USB interface will remain active, directly
supplied from the USB bus. A new print job with the
standard drivers will reactivate the printer without any
loss of data. In a USB suspend mode, the internal USB
interface is also turned off. The printer will 'go to sleep'
after the set sleep time period.

The GPT-437x-Flash-BT corresponds to the BT speci-

with a customary BT dongle that comes with a virtual

Recommended settings of the printer: 115,200, n, 8, 1,

The printer responds to an inquiry scan with its name
"GPT-4378/79-Flash" and its BT address. However, it
can also be addressed directly, without a scan, with its
BT address.
A "BT connect" activates the printer. The printer will
maintain a connection until it goes into sleep mode.
The online power consumption of the printer with an
active BT link is about 35mA. The sleep mode discon-
nects an active connection and activates the BT sniff
mode. In this mode, the printer scans its environment for
possible calls every 1.25 seconds. During these inquiry
scans, it remains visible and responsive. It will then take
about 2-3 sconds to establish a connection.
The power consumption in this mode is about 1.5mA.
When the printer is reactivated through the feed button,
the BT tranceiver will remain in sniff mode. After the set
time period, the printer will go back into sleep mode. The
power consumption in this mode is about 5mA.
If you are not planning to operate the printer for several
days, switch it off with the OFF/NEXT button. After the
power is turned on, it will take a minimum of 10 seconds
for the printer to become ready to recieve data.

The magnetic strip can contain up to three tracks with serial data. The recording density and the number of bits
per character of each track are different in accordance with ISO 3554. They result in the maximum number of cha-

For track 1, the maximum is 79 characters, for track 2 , it is 40, and for track 3, it is 107 characters, including the
start and the stop character.
In accordance with the norm, track 1 and 2 are only read during operation. Track 3 is the only one that is also

Almost all commands that the printer can receive
through the interfaces can be put into the batch files.
When a batch file is processed, the commands it con-
tains are added to the data stream of the print pro-
gram 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 con-
tain text and graphics.
The file structure consists of one TINIT, which is pro-
cessed with each system boot-up, as well as 10 files
that can be used freely, which are retrieved by com-
mand. 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 (FLASH).
When a filed is retrieved, the printer will check, if it
contains data in the EEPROM. If it does not, the file
will be processed in the FLASH. This allows FLASH
files to be over-written.
The following batch files are accessable:

If large pieces of text or graphics have to be filed in the
batch files, e.g. in order to be able to print out logos,
advertising text, or operating instructions with the
push of a button,insted of the serial EEPROM with a
capacity of 8KByte EEPROM (about 6KBytes usable
for logo printing) a 32 KByte type can be installed.

A special printer driver is available for creating logos.
(logo.drv)
This Windows driver moves logos that have been cre-
ated with a graphics program to a usable file for the
printer. The new file contains the command for saving
the logo file in the printer, however, the 16 bits file
length minus the 6 bytes still have to be entered in the
byte positions 8 and 9. Please refer to the software
manual about saving files in the EEPROM.

After a hardware RESET (turning on the power supply),
the controller will first process the basic initialization
from the flash program and the batch file "TINIT-F".

Then it will check, whether a TINIT file already exists in
the EEPROM. If it does exist, it will process these com-
mands and will then be ready for operation. if not, the
TINIT is processed in the flash with the factory settings.

version 2.0. In earlier versions, the menu section is se-
parate and cannot be changed.)

The OPD-Menue is a tool to manipulate the TINIT in the
EEPROM. The OPD-Menue requires a certain structure
in the menu section in order to work.
If this structure is changed, the menu may no longer
work properly.
The following TINIT file is a basic file to be changed by
the user.
It can be downloaded from the Internet at this URL:
www.oem-printer.com/flash/xxxx.
The file will erase the TINIT, while printing all actions
(Italics).
By changing the parameters in the menu section, the
menu can be preset.
In the unused section, any commands may be entered.
If a command from the menu section is repeated in the
unused section, this value can no longer be changed
through the menu.

Not every error means that there is a printer error that can not be cleared by the user.
Users will save time and money by recognizing and clearing simple errors on their own.
The following tips are meant to help with this:
HH
HHaa aarr rrdd ddww wwaa aarr rree ee RR RREE EESS SSEE EETT TT:::: Triggered by removal of the power source (battery) and replacement after a short break. This
causes the printer to be set to the parameters in the batch file TINIT-F or TINIT-E. See Batch Files on page 14.
TT

HH
HHee eexx xxdd dduu uumm mmpp pp mm mmoo oodd ddee ee:::: Is triggered by holding down the FEED button for more than 3 seconds after reactivation from
power OFF, if no paper is inserted. After the paper has been inserted, the printer prints the data it recieves as hex
numbers with the appropriate ASCII code without interpreting the data. This shows, which information the printer
"reads" from the recieving data.

The printer seems to be printing. Pa-
per is transported, but is not blacke-
ned.
Printer can not be reactivated by
pressing the FEED button.
Paper: Wrong side toward print
head. Only one side of the paper
can be printed on.
No power.

Insert paper correctly. The thermo-
sensitive 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, pres-
sing down. The friction heat causes
the thermosensitive side to blacken.
Check power supply.
Recharge battery. The green LED
should light no later than after 1 mi-
nute.
LED goes out just briefly at the begin-
ning of printing.
The printer only prints a few dots in
one line.
The paper feed works, but the self
test does not.
The printer only prints a few charac-
ters in one line. If more is entered, it
stops printing completely.
The power supply is not optimal.

supply with sufficient dimension and
short feed lines. Check all connecti-

Since high peak currents occur with
thermal printers, even the smallest
transfer resistances can result in into-
lerable voltage drops. In this case, no

A
fter a few characters, the printout
starts to be incomplete.
The printer prints the wrong charac-
ters.
The printer buffer is "over-run" (256
bytes), causing a loss of data. The
print data transmitter shows no re-
action to handshake.
Interface problem. The transmission
is faulty. (Characters of the upper

EE
EExx xxtt ttee eerr rrnn nnaa aallll pp ppoo ooww wwee eerr rr ss ssuu uupp pppp ppllllyy yy:::: Bad ground
