B
^ADB
Write one address along the tag and the second across:
^XA
^LH30,
100
^FO70,
60^AD^FDWWW.AskQA.RU^FS
^FO20,
10^ADB
^FDWWW.URN.SU^FS
^XZ
The result will be something like this:

In short: ^A,5040^FDTEXT
Details:
Let's take our previous one. example and add command parameters
^A
For example, instead of ^AD write ^AD,
130,20
^XA
^LH30,
100
^FO70,
60^AD,
