How can I write a serial text string (ASCII) to a Zebra printer on COM1 without a 'GetCommError' being generated by WIN20000?

I don't know how it could happen.
This is the right one.

Thanks for the input. I have not looked at your VI yet, but I had sucess by creating sub-Vi's to add the ZPL code and creating an input strings and then sending it to the array. I also moved the Serial Port Init.vi to the '0' sequence. I have attached the VI if you are interested.

I am answering my own question. See attached VI. I created sub-vi's to create strings of aquired data and Zebra ZPL commands. The sub-vi's are sent to an array which is sent to the srial port vai the Serial Write Vi.

I have Zebra  TLP3844-Z on USB and I can't found way to print label. I have .txt (ZPL) file and with DOS Print command (to printer on LPT port) everything is OK, but I must use 2 printers and target PC haven’t any LPT port.
