Thank you Klaus.

Hi,

it depends on protocol and communication commands.

Maybe here is a specialist knowing exactely this printer....
But i´d look at the manufacturer´s web pages, or directely ask the manufacturer.

hello,

Compatible with ESC/POS command set, more characters style setting commands
Serial(RS-232C ) interface

maybe these old document can help you.. ESC command for printer
just try to send direct command with a RS232 terminal to the printer

like VBRAY terminal , easy to send ESC sequence of char
with programmable key or script.

I have tried sending commands by RS-232. but its not working.

I am working on PIC16f877a. Using CCS Compiler.

I am sending data like:
printf("1111111111"); //Data to be printed on paper.
putc(13); //CR decimal code. print command

Its not working. After sending "CR" command 20 to 25 times, It prints one line in chinese.

Plz help.. can some provide example-code of few line to print simply "hello world".

Hi,

try: 9600 baud. 8N1.

Read command set:

Maybe try: [ESC] "R" 0
to switch from chinese to american character set

Some years ago there was a thread about the same printer. Maybe you can contact the poster and ask about his experience.

Good luck
