1. Need to print Code 128 barcodes on EM205 thermal printers. I am using arduino library here:

2. printer is EM205 running at 9600 baud rate. I am able to print characters & barcodes as attached.

3. barcode in pic is 14 characters max as u can see & below is code for that:

printer.printBarcode("12345678901234", CODE128);

4. Problem is when i increase the characters to 15 or more, nothing prints. How to solve this? I need to printer around 55 characters. Untitled.png
