First of all, thank you very much for sharing your code, i´m working with a Zebra printer and it has been very useful to connect with the printer, but i have some doubts about how to send the data I want to print. I was wondering if you have some simple example about how to form the string you send to the printer. What I have done is creating a DB where a I have included an ASCII character in each byte, and all the characters joined form the message I want to print (ZPL language symbols included). Then I put this DB as an imput of TSEND FB. Is there another way to manage this data to print? I can´t test my code until next week, and I have serious doubts about this part...
