가 is the subject particle. It marks 프린터 as the thing that is doing or experiencing the action: the printer is working.

In this sentence, 프린터가 feels natural because it presents the printer as the main subject being talked about right now.

A learner might compare it with 프린터는:

• 프린터가 다시 작동해요. = The printer is working again. / It’s the printer that’s working again.
• 프린터는 다시 작동해요. = As for the printer, it works again. This sounds more like a contrast or topic-setting sentence.

So 가 is the more straightforward choice here.

다시 means again.

So it shows that the printer was not working before, but now it has returned to a working state.

It can also mean back or once more in other contexts, but here again is the most natural meaning:

• 다시 시작해요. = We start again.
• 다시 왔어요. = I came back.

The dictionary form is 작동하다.

This is a verb meaning to operate, to function, or to work for a machine or device.

The form 작동해요 is the polite present-style form built from 작동하다:

• 작동하다 → 작동해요

This 하다 pattern is very common in Korean, especially with words of Sino-Korean origin.

Both are possible, but they differ in politeness.

• 작동해요 = polite, everyday standard speech
• 작동해 = casual/plain intimate speech

So:

• 프린터가 다시 작동해요. would be appropriate in most normal conversations
• 프린터가 다시 작동해. would sound more casual, like talking to a close friend or someone younger

For learners, -해요 is usually the safest form to use in everyday situations.

Korean present-style forms often cover both simple present and progressive meanings, depending on context.

So 작동해요 can mean:

• works
• is working
• is functioning

In this sentence, because of 다시, English will usually translate it as is working again or works again. The exact English wording depends on context, but Korean does not need a separate form here.

It is mainly used for machines, devices, systems, programs, and mechanisms.

So it sounds very natural with things like:

• printers
• computers
• engines
• apps
• systems

Examples:

• 컴퓨터가 작동해요. = The computer works.
• 이 버튼이 작동하지 않아요. = This button doesn’t work.

For people, you would not normally use 작동하다. It is a machine/system kind of verb.

Yes. 프린터 is a loanword from English printer.

Korean often borrows technology-related words from English and writes them in Hangul. The pronunciation is adjusted to fit Korean sound patterns, so printer becomes 프린터.

Many device names in Korean are loanwords:

• 컴퓨터 = computer
• 모니터 = monitor
• 프린터 = printer

So this is a very normal and useful vocabulary pattern to notice.

Not naturally in this case.

되다 often means to become, to be possible, or sometimes to work in conversational Korean, but with machines it is more common and clearer to use:

• 작동하다 = to function/operate
• sometimes 되다 in casual speech, depending on context

For a printer specifically, 프린터가 다시 작동해요 sounds more precise and standard.

A speaker might say something like 이제 프린터 돼요 in casual conversation, meaning The printer works now, but that is more colloquial and context-dependent.

Yes. It usually implies a change of state.

프린터가 다시 작동해요 suggests:

1. the printer was not functioning before
2. now it is functioning again

So the sentence does not just describe the printer in general. It usually reports good news or a recovered condition, like after fixing a problem.

A natural negative form is:

프린터가 다시 작동하지 않아요.

This means The printer doesn’t work again or, depending on context, The printer still isn’t working is what English speakers might expect, though that exact nuance may be expressed differently.

Another simple negative without 다시 is: 프린터가 작동하지 않아요. = The printer isn’t working.

So -지 않아요 is the standard polite negative pattern.

It is pronounced roughly like jak-dong-hae-yo.

A few helpful notes:

• 작 sounds close to jak
• 동 sounds like dong
• 해요 is often pronounced smoothly, almost like 해요 / hae-yo, and in fast speech it can sound a little closer to 해여

So the full sentence is approximately: peu-rin-teo-ga da-si jak-dong-hae-yo

The romanization is only an approximation, but it can help at the beginning.
