Is Barcode ever used without text?
Maybe we don't need another variant, just always add the text below.
Comment 2 kabilo 2022-02-23 14:44:41 UTC 
Text label printing (and possible alignment) is usually an optional item in specialized programs. I always print it, Thanks

Yes.

No. Text should always be an optional addon.

(Often enabled by default, but should still be optional.)

Having text along with the barcodes is very important for things like ISBNs on books or back of book covers.

This allows a human to read what the heck the barcode says, and not *require* a scanning device to tell them.

The best document I ever came across on all the different barcode variants/types was for a LaTeX package called:

- pst-barcode

A PDF of their documentation can be found here:

- http://mirrors.ctan.org/graphics/pstricks/contrib/pst-barcode/doc/pst-barcode-doc.pdf

Text/Numbers can be written:

- Below/Above the barcode.
- "Inside"/"Overlapping" the barcode slightly.
- Along the whole length of the barcode
   - Where each text character goes below its equivalent barcode symbol.
   - So each letter could have large "gaps" between them.
   - (Or, text just written normally + centered below barcode.)

See the documentation for all sorts of example images and detailed descriptions.

I suspect for this enhancement, it would be okay just to produce:

- Centered text.
- Below the barcode.

and have a checkbox to turn it on/off.
