GeBE E + F GmbH • www.oem-printer.com • SMAN-E-471-V2.5 • Thermal Printer GPT-4378 /-4379
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, bidirectional,
dot to dot IR-protocol.
GeBE Doc.No. MAN-E-395
• HP-IR: Unidirectional IR transmission
GeBE Doc.No. MAN-D-416
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-437x.
The internal IR tranceiver is installed directly below the
red foil window (10). The GPT-4379 has an LED next to
the transceiver that signals any IR communication. It is
important to consider that infrared transmissions only
work "at sight". The radiation angle is about +/-15
degrees. The transfer distance, which also strongly
depends on the efficiency of the opposite side, is
about 60 cm. It can be expanded to < 3 meters by
installing a booster-IR LED.
Use of the Sleep Mode
In the setting "IrDA "or "GeBE IR", the IR receiver will
even be active in the sleep mode, so the device will not
have to be switched 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. The data transmission is processed in
CRC protected blocks.
With each transmission confirmation, the printer status
is sent back to the host.
The implementation is easy to realize. The protocol is
disclosed.
5.2 Infrared Interfaces
IrDA Protocol
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 problems 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.
