The terms pretty-print(er,ing) are often used in programming to designate a kind of function that outputs a human-readable text, in a more pleasant way than a "raw" representation of the data being printed.
I found the following translations online, but I don't know which one (if any) is more commonly used (or if the English form is used without translation):
- Impressão bonita
- Impressão formatada
- Impressão alinhada
- Impressão elegante
