Sé que es una molestia volver a imprimir todo, pero así evitamos problemas después.

Because sé here is the first-person singular form of saber: I know.

The accent distinguishes it from se, which is a very common pronoun in Spanish.

• sé = I know
• se = himself / herself / itself / themselves, or part of various pronominal/passive structures

So in Sé que..., the accent is necessary because it means I know that....

Because ser is used to identify or describe what something is, while estar is used more for states, locations, or conditions.

Here, una molestia means a nuisance / a hassle / an inconvenience, and the speaker is classifying the action as that kind of thing:

• Es una molestia = It is a nuisance / hassle
• Está una molestia is not correct Spanish in this context

So es is the natural choice.

In this sentence, molestia means something like:

• a nuisance
• a hassle
• an inconvenience
• a bother

So es una molestia volver a imprimir todo means that reprinting everything is annoying or inconvenient.

A useful thing to remember is that molestia is a noun, while molesto/a is the adjective:

• Es una molestia = It’s a hassle
• Es molesto = It’s annoying

Volver a + infinitive is a very common structure meaning to do something again.

So:

• volver a imprimir = to print again / to reprint
• literally: to return to printing

Other examples:

• volver a llamar = to call again
• volver a intentar = to try again
• volver a empezar = to start again

It is one of the most natural ways in Spanish to express again with an action.

Yes. Reimprimir is also correct and means to reprint.

So these are both possible:

• volver a imprimir todo
• reimprimir todo

The difference is mostly one of style and frequency:

• volver a imprimir often sounds more conversational and everyday
• reimprimir is a bit more compact and can sound slightly more technical or formal depending on context

In ordinary speech, many people would naturally say volver a imprimir.

Because the verb is imprimir, which means to print.

Its forms include:

• imprimo = I print
• imprime = he/she prints
• imprimimos = we print
• impreso or imprimido = past participle, depending on use

This is simply the standard verb for printing documents.

Here todo means everything.

So:

• imprimir todo = to print everything

It is singular because it refers to the whole set as one total thing, not to individual countable items.

Compare:

• imprimir todo = print everything
• imprimir todos los documentos = print all the documents

Both are possible, but todo is broader and more general.

Because todo is the direct object of the infinitive imprimir.

So the structure is:

• volver a imprimir todo
• literally: to print everything again

This word order is very normal in Spanish. English does the same:

• to print everything

You could not naturally say todo imprimir here.

Here así means this way, like this, or that way.

So:

• pero así evitamos problemas después
• but this way we avoid problems later

It refers to the action just mentioned: reprinting everything. The idea is:

If we do it this way, we avoid problems later.

Spanish often uses the present tense to talk about:

• a general truth
• an immediate consequence
• something that will happen as a result of the current action

So así evitamos problemas después means something like:

• that way we avoid problems later
• that way we’ll avoid problems later

In English, we’ll avoid may sound more natural in some contexts, but Spanish very commonly uses the present here.

Yes, literally it means we avoid.

But in context, this we is often inclusive and practical rather than heavily literal. It can mean:

• we, all of us involved
• we as a company/team
• we in the general sense of this helps us avoid problems

Spanish uses this kind of we very naturally in workplace and everyday situations.

Because Spanish often omits the article when speaking in a general, non-specific way.

So:

• evitamos problemas = we avoid problems
• evitamos los problemas would sound more like we avoid the problems, meaning specific problems already identified

Here the meaning is general: reprinting everything now helps prevent trouble later in general.

Because después on its own means later / afterwards.

• después = later
• después de = after
  • noun/pronoun/infinitive

Examples:

• Te llamo después. = I’ll call you later.
• Después de comer = After eating
• Después de la reunión = After the meeting

So in evitamos problemas después, después simply means later.

Because que introduces a subordinate clause after verbs like saber, creer, pensar, and decir.

So:

• Sé que es una molestia...
• I know that it’s a hassle...

In English, that is often optional:

• I know it’s a hassle
• I know that it’s a hassle

In Spanish, que is normally required here.

Yes, it sounds very natural in Spain, but it would also be understood and used in many other Spanish-speaking places.

A few notes:

• molestia and así evitamos problemas después sound very standard and neutral
• In Spain, this kind of sentence is common in office, school, or administrative contexts
• The tone is polite, practical, and slightly reassuring

It is basically saying: I know this is annoying, but it will save us trouble later, which is a very common real-life structure in Spanish.
