Text wrapping in a cel with formula

If your Dymo app is picking up the Line feeds, then an alternative might be to pad each line to the same (maximum allowable) length using

= CONCAT(LEFT(header & ": " & Address & REPT(" ", 32), 32))

where header
= {"Company","Contact","Address","City   ","Country"}

It is such a basic requirement, though, that the app must accept some combination of <LF>, <CR> and <FF> as control characters.
