58MM Portable MINI Thermal Printer
RS-232 is developed according to the EIA standard asynchronous
transmission, the specifications are as following:
Data transmission: serial interface
Synchronization: asynchronous
Signal Level: RS-232 level, logic 1:-5.4v, logic 0 : +5.4v
Hardware Flow Control: None
Baud rate: 2400pbs to 115200pbs is optional
Data word length: 8 bits
Stop bit: 1bit
Parity: None
4-1. RS-232 Serial (COM) Interface
Users can get the current baud rate from the printer self-testing page.
Serial cable: We have made the cable specially using mini port like Mini
USB port which connects the printer .The following picture shows the
signal definition of the RS-232 Serial interface:
The connection between the printer and host follows the following
rules:
Printer
TXD
RXD
GND
Host
RXD
TXD
GND
Printer
RXD
GND
Host
TXD
GND
However, the printer usually works only on r eceiving data, it doesn’t
have to respond anything back to the host , then TXD signal can be ignored ,
and then the connection can be sampled as following:
Bluetooth is a proprietary open wireless technology s tandard for exchanging
data over short distances ( using short-wavelength radio transmissions in the
ISM band from 2400–2480 MHz) from fixed and mobile devices,c reating personal
area networks (PANs) with high levels of security.
4-2. Bluetooth Connection
4-2-1. Bluetooth specification
Using blueCore4-Ext chipset, fully compatible with Bluetooth 3.0;
High-sensitivity receive signal, small size, lower consumption
Supporting 1200bps ~ 1382400bps variety of baud rate;
Supporting SPP agreement, the maximum transfer speed is up to 3Mbit / s;
4-2-2. Use “AT” command to modify Bluetooth Module’s parameters
Notice: The following changes can’t be done by user, these should be
done in factory by Manufacturer. So if user wants to change these parameters,
please inform our sales person before ordering our printers.
Modify name---Send character string “AT+NAMEXXXX, feedback “Okname;
For example, if you want change name to “Bluetooth Printer, please
send string “AT+NAME Bluetooth Printer.
Modify PIN code--- Send character string “AT+PINXXXX, feedback “Oksetpin”;
For example, if you want change PIN code to “8888”, please send string AT
+PIN8888.
