This website is great for testing against: http://labelary.com/viewer.html.
Assuming you don't want the position to move it should just be changing
^BY2,2,20
to
^BY1,1,10
The API Reference guide can be found https://www.zebra.com/content/dam/zebra/manuals/en-us/software/zpl-zbi2-pm-en.pdf
Don't forget to take into consideration the print density, i.e. at 152 DPI you probably want something like
^FO150,20
^BY1,1,10
But at 600 DPI
^FO550,80
^BY4,1,40
EAN-13 Text Modifications
If you are using the the inbuilt EAN-13 text function i.e. ^BEN,40,Y,N you can't modify the text. It is to a standard. You can however add your own text e.g.
^XA
^FO100,20
^BEN,40,N,N
^FD011601512345^FS
^CF0,48
^FO90,80^FD011601512345^FS
^XZ
^BEN,40,N,N The first N tells the printer to not generate the number underneath.
^CF0,48 Is the select font function of the printer, its first parameter is a default printer font (can be found in the Standard Printer Fonts section of the link above). The second parameter is the font height. If needed there can be a 3rd parameter which alters the font width, though isn't needed.
^FO90,80^FD011601512345^FS Sets the field origin of the string starting at the location defined by ^FO. ^FDXXXXXXXX^FS draws the string.
