É importante revisar a pontuação antes de imprimir o texto.

In Portuguese, É importante... is a very common impersonal structure meaning It is important....

The it in English is just a dummy subject, but Portuguese often leaves that kind of subject out:

• É importante estudar. = It is important to study.
• É bom descansar. = It is good to rest.

So É importante revisar a pontuação... is a natural way to say It is important to review the punctuation...

É with an acute accent is the verb ser in the he/she/it is form:

• ele é
• ela é
• é importante

The accent matters because e without an accent is usually the conjunction and.

So:

• É = is
• e = and

Because after expressions like É importante..., Portuguese often uses an infinitive verb to express a general action:

• É importante estudar.
• É necessário dormir bem.
• É melhor esperar.

Here, the actions are:

• revisar = to review
• imprimir = to print

So the sentence literally follows the pattern:

• It is important + to review + before + printing/to print

Because antes normally combines with de before a verb in the infinitive.

So the standard pattern is:

• antes de + infinitive

Examples:

• antes de sair = before leaving
• antes de comer = before eating
• antes de imprimir = before printing

So antes de imprimir o texto is the correct structure.

Portuguese uses definite articles more often than English does.

So where English might say:

• review punctuation

Portuguese naturally says:

• revisar a pontuação

This is very normal. A few similar examples:

• abrir a porta = open the door
• lavar as mãos = wash your hands / wash the hands
• estudar o português = study Portuguese

So a pontuação is not unusual at all.

For the same reason: Portuguese often prefers the definite article where English may omit it.

• imprimir o texto = print the text

If you say o texto, you are usually referring to a specific text, such as the one being discussed.

Without the article, imprimir texto would sound unnatural in this sentence.

Here, pontuação means punctuation: commas, periods, question marks, and so on.

Be careful, though: in other contexts, pontuação can also mean score or points, depending on the situation.

Examples:

• A pontuação do texto está errada. = The punctuation in the text is wrong.
• A pontuação do jogo foi alta. = The score in the game was high.

In your sentence, it clearly means punctuation.

Sometimes yes, but revisar is the more natural choice here.

• revisar = to review, revise, check carefully
• rever = to see again, review, reconsider

For checking punctuation before printing, revisar sounds more precise and idiomatic.

Natural:

• É importante revisar a pontuação...

Less natural in this specific context:

• É importante rever a pontuação...

Yes. Imprimir is the standard verb for to print.

Examples:

• Vou imprimir o documento. = I’m going to print the document.
• Você imprimiu o arquivo? = Did you print the file?

In everyday Brazilian Portuguese, this is the normal verb you would use for printing something on paper.

Because Portuguese usually keeps the action order very straightforward:

1. revisar a pontuação = review the punctuation
2. antes de imprimir o texto = before printing the text

So the sentence is built like this:

• É importante
• revisar a pontuação
• antes de imprimir o texto

This is the most natural order in Portuguese.

A common way would be:

• Você deve revisar a pontuação antes de imprimir o texto.

Or, a little softer:

• É importante que você revise a pontuação antes de imprimir o texto.

The original sentence is more neutral and general. It sounds like advice or a general rule, not directed at one specific person.

A simple approximation is:

EH im-por-TAHN-cheh reh-vee-ZAR ah pon-too-ah-SOWN AN-cheez jee im-pree-MEER oo TEX-too

A few pronunciation notes:

• É sounds like eh
• importante in Brazil often sounds like imporTANchi
• revisar has stress on the last syllable: reviSAR
• pontuação has stress on ção
• antes de often sounds like antes dji / dee, depending on accent
• imprimir has stress on the last syllable: impriMIR

Yes. That is very normal.

English often uses before + -ing, but Portuguese usually uses:

• antes de + infinitive

So:

• before printing → antes de imprimir
• before leaving → antes de sair
• before eating → antes de comer

You do not need a gerund here in Portuguese.
