Thermal inkjet printer with node red

[danhoo1]

Hello y'all. I have a HX Nitro Printer that accepts dynamic text over wifi and im wondering if someone could give me a bit of a head start on how i would setup a flow that would change the text of what the printer is printing from node red. see attached for the manual they sent me on the commands. Im a bit new to this lol

Hi @danhoo1

According to the manual, it accepts HTTP POST commands, and the data being sent needs to be XML.
Naturally this will be guess work, but according to the manual, something like this, is what you are looking for.

<Cookie>
	<Auth_token_1109>{Password}</Auth_token_1109>
</Cookie>
<APCMD>
	<CTEXT>
	    <POS>20,10</POS>
	    <TXT>ABC Company</TXT>
	</CTEXT>
</APCMD>

Where {Password} is your MD5 hashed password, converted to a Base64 string.

Using the HTTP Request Node, will be the node to use here, and the Template Node.
The below will get you started, but you may need to seek support from the manufacturer, if something isn't right - as said, this is just a guess.

You will need to set the URL in the Request Node - and connect it to the Template Node of course (which creates the XML body)
