It is the standard Mandarin pattern for if...then....

• 如果 = if
• 就 = then / in that case

So:

• 如果学校那边不能打印，我们就去图书馆复印资料。 = If the school side can’t print, then we’ll go to the library to copy the materials.

A few useful notes:

• In English, then is often optional, and in Chinese 就 can also sometimes be omitted.
• But 如果...就... is a very common and natural matching pair for conditional sentences.

学校那边 means something like over at the school, on the school side, or at the school over there.

那边 does not just mean a literal side. In everyday speech, it often means:

• that place over there
• that area
• that location associated with something

So 学校那边 sounds natural when referring to the school as a location or area.

Compare:

• 学校不能打印 = the school cannot print
• 学校那边不能打印 = over at the school, printing isn’t possible

The version with 那边 feels a little more conversational and location-based.

Both can refer to there, but they are not exactly the same.

• 那里 = there, a straightforward location word
• 那边 = over there / that side / that area

In this sentence, 学校那边 sounds more like over at the school or on the school side, which is very natural in spoken Mandarin.

If you said 学校那里, people would still understand you, but 学校那边 often sounds smoother and more idiomatic in this kind of context.

不能 means cannot / be unable to / not be allowed to.

So:

• 不打印 = does not print / will not print
• 不能打印 = cannot print

In this sentence, the meaning is not just that the school doesn’t print, but that printing there is not possible. That is why 能 is important.

So 不能打印 gives the idea of inability, lack of service, or impossibility.

This is a very useful distinction.

• 打印 = to print
  • usually from a computer, phone, or digital file onto paper
• 复印 = to photocopy / make a copy
  • usually copying an existing paper document

So they are not interchangeable.

Examples:

• 打印文件 = print a document
• 复印身份证 = photocopy an ID card

In your sentence, the speaker is saying:

• if printing is not possible at the school,
• then they will go to the library to copy materials

That may sound a little unexpected in English, but in context it can make sense if the 资料 are paper materials that need to be duplicated.

资料 is a broad word that can mean:

• materials
• documents
• information
• data
• reference materials

In everyday situations like this, 复印资料 usually means photocopy materials/documents.

It is broader than some English words, so the exact translation depends on context.

For example:

• study materials
• application documents
• reference handouts

So here, 资料 is best understood as materials/documents rather than abstract data.

Mandarin word order usually puts the destination or place before the main action that happens there.

So:

• 去图书馆复印资料 = go to the library to photocopy materials

The order is:

1. 去 = go
2. 图书馆 = library
3. 复印资料 = photocopy materials

This is very natural in Chinese. It is similar to saying:

• I’m going to the library to copy some materials

Putting 复印资料 before 去图书馆 would sound wrong or unnatural because the location needs to be established first.

Yes, it could be omitted if the subject is already clear from context.

For example:

• 如果学校那边不能打印，就去图书馆复印资料。

This is still grammatical and natural.

However, 我们 is included here because it:

• clearly states who will do the action
• makes the sentence more complete
• can add a slight sense of contrast or planning: as for us, we’ll go...

Mandarin often omits subjects when they are obvious, but including them is also very common.

Yes, sometimes.

You could say:

• 学校那边不能打印，我们就去图书馆复印资料。

This still clearly means something like:

• If they can’t print at the school, we’ll go to the library to copy the materials.

In conversation, Chinese often drops 如果 when the conditional relationship is already obvious from context, especially if 就 is still there.

That said, keeping 如果 makes the conditional structure more explicit and is especially helpful for learners.

It does more than just mechanically translate then.

Here, 就 helps show:

• result
• quick consequence
• a natural next step

So 我们就去图书馆 feels like:

• then we’ll just go to the library
• in that case, we’ll go to the library

It often gives the sentence a smooth if X, then Y logic.

In many sentences, 就 can also suggest that something follows naturally or immediately from what came before.

Most likely it means printing is not available there or they can’t print there.

By itself, 不能 can mean either:

• cannot
• must not / not allowed to

But in this sentence, the most natural interpretation is practical inability, such as:

• the printer is unavailable
• that location does not offer printing
• printing there is not possible for some reason

So learners should understand it here as can’t, not as a rule or prohibition unless the wider context says otherwise.
