Other Parts Discussed in Thread: DXP
 I am using DRV8834PWP texas instruments Stepper motor driver for simultaneous print head movement while printing. 

I am not at all understanding how to feed characters to printer LTP01-245-11/12/18 and move stepper motor along with it and how to convert the characters to bit map image. 
I am using RS232 interface for interfacing between Microcontroller.

    Suraj,

    I think your question is related to printer mechanism and how to use micro-controller to feed/ print the characeters and drive stepper motor.

    You should refer to printers technical reference manual which provides all the relevant information regading printing the characters, inlcuding excitation sequence to drive the stepper motors.  For queries on MCU, You should ask the questions to relevant micro-controller forums depndiding upon the micro-controller used in proejct.

    Best Regards

    Hi Dilip , 

    Here is the link which gives you a software which will convert your data into bit map images http://en.radzio.dxp.pl/bitmap_converter/

    and also if you want to hard code it then include the library of converting the matter into bit map like in Fax systems.
