Hi,
I wanted to print text using the epson lx300 dot matrix printer by sending command through AVR microcontroller.
Command will be sent through Embedded C language.
Parallel port interface is used to connect between microcontroller and printer.
Anyone help me pls?
 

your c program can send the ascii codes of characters to be printed to lx300.
 

first find out the parameter that needs to be inisialyzed for the printer.
than you can make the inisilisation for the serial comm as a procedure that can be called any time you wnt to send your command to the printer. well i recommend that the avr only used as a bridge between PC and printer nad other device u used. because u need to descript every charachter low case up case etc that might be make your avr work too much and crash or hang..i hope that can help.
