I think that you should use a single _, not __. But I’m not sure.

3

Remember the same code is working for standard POS format. My question is why is not working on the custom format?

4

Anyone to help me please

What does it have in the “Print Format Type” field? Probably it did not copied correctly.

6

It has JS

7

What’s the name of the print format? POS Invoice or Point Of Sale? How do you open it?

8

mainPOS is the name. What do you mean how to open it?

9

What’s the original name, the one that you duplicated, I’m trying to recreate the error. How do you access the print format, because I don’t see any of the “JS” print formats in the options.

The original is called POS Invoice. I created it by clicking on menu>duplicate. Then gave it a name. As shown

Try selecting “Jinja” in Print Format Type

I get this error when trying to print. I get this on print preview

I still get jinja2.exceptions.UndefinedError: ‘__’ is undefined

I got it working by duplicating and changing the Print Format Type to Jinja, do you modify something more?
