Thanks That would depend on your printer. Just check the pin-outs and ensure the transmit goes to the receive on the other device and vice versa. If your printer needs hardware handshaking, you may need a device in between (PLC and printer)to handle that for you.

I can send a string of characters, but I have a problem: The press is only if the printer buffer is full. So I have to send 42 characters at a time.

The manual in the "Table 12-22," says "STRING / The LENGTH parameter contains the number of characters to be Transmitter. Only the characters of the String are Transmitted. The maximum current and length bytes of the string are not Transmitted. " How I can fix it? thank you very much
