Hi,

I have to send data to a Zebra printer connected via Ethernet with a S7 315, and I have some doubts about how to form the data to send. 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... Thanks.

Hello totgol;

Have a look at the following discussion (from another automation forum), thereyou will find suggestions and sample code to connect a S7 PLCto a Zebra printer over TCP/IP:

Hope this helps,

I think my problem is that Zebra printer is connected via Cp 343-1, and the example I followed and above-mentioned uses open communications via T-Blocks. In my case Isuppose I have to configure printer in Netpro before using T-Blocks. Is it right?
