Hello demigods!  
I'm working to send data from node-red to a domino printer.  
The protocol is CodeNet and from what I understand I have to open the tcp door and send a character frame. Can you help me?  
Printer: Domino Ax 150 i  
Ip: 10.0.0.21  
Port: 7000

thank's

I'd suggest you start simple...

Inject --\> TCP Request node --\> Debug (show full mesage)

Set the Inject to send either a string (ASCII mode) or a buffer (HEX mode).

Build some example strings / buffers and see what happens.

The format of the ASCII / Buffer will be determined by the information in the manual and what you want to send.

Steve-Mcl.

I will follow your suggestions, but I need help to get started, I have little experience.  
Is it correct to open the door?

Tanks!

Half correct. Steve suggested using the tcp request node ( as that has an output and will show you any replies). But yes use that port and ip

Now you need to send a correct message. I think it will need to be a binary buffer ( so that 1b is a byte 0x1b etc)

Unfortunately, I was unable to separate as suggested.  
Even with the correct frame in the message, will I have to queue in hex?
