kono siryou no insatu wo onegaisimasu.

この and これ both relate to this, but they are used differently:

• この must come before a noun: この資料 = this document / these materials
• これ stands by itself: これは資料です = This is a document

So in this sentence, 資料 is the noun being modified, so この is the correct form.

Here, の connects two nouns.

• 資料 = document / materials
• 印刷 = printing

So 資料の印刷 means the printing of the document or printing this document.

The の does not just mean possession. It often links nouns more broadly, showing a relationship between them. In this case, it tells you what is being printed.

印刷 is a suru-noun. That means it can work:

• as a noun: 印刷 = printing
• as a verb with する: 印刷する = to print

In this sentence, it is being used as a noun because the pattern is:

• [noun phrase] をお願いします

So この資料の印刷をお願いします is literally something like I request the printing of this document.

A more direct verb version would be:

• この資料を印刷してください。

Both are natural, but the version with お願いします sounds more like a polite request in an office or service setting.

Because the thing being requested is the whole action/event phrase:

• この資料の印刷 = printing this document

Then をお願いします attaches to that whole noun phrase.

So the structure is:

• この資料の印刷 = the printing of this document
• をお願いします = please do that / I request that

If you used a verb instead, then 資料 would take を:

• この資料を印刷してください。

So the particle placement changes depending on whether Japanese is using a noun-based request or a verb-based request.

In this sentence, お願いします is a polite request expression. It often works like please in English, but its literal feeling is closer to:

• I ask/request this
• Please take care of this
• Please do this for me

In business Japanese, [noun] をお願いします is extremely common and sounds polite and natural.

So この資料の印刷をお願いします is a standard, professional way to ask someone to print the document.

Usually, yes. Or at least it sounds a bit more indirect and businesslike.

Compare:

• この資料を印刷してください。
  = Please print this document.

• この資料の印刷をお願いします。
  = I’d like to ask for the printing of this document.

The second version is very common in workplaces because it sounds smoother and less direct. Both are polite, but お願いします often feels more natural in requests between coworkers, staff, or customers and employees.

Not always.

• 印刷 usually means printing, often from a computer file, data, or a prepared document
• コピー usually means making a copy / photocopying

So if you mean print this file/document, 印刷 is appropriate.

If you mean make photocopies of this paper, Japanese speakers may prefer:

• この資料のコピーをお願いします。

In real life, context matters, and sometimes either word can be understood, but the nuance is different.

Japanese often leaves out subjects and other information when they are obvious from context.

So this sentence does not explicitly say:

• who should print it
• who wants it printed

That is normal in Japanese. In context, it is understood that:

• the speaker is making the request
• the listener is the one expected to do it

This omission is one of the most common features of natural Japanese.

The spaces are only there to help learners see the parts of the sentence more clearly.

Normally, Japanese is written without spaces:

• この資料の印刷をお願いします。

So the spaced version is a teaching aid, not standard writing.

No, that would be unnatural and grammatically wrong.

You generally have two good patterns here:

• この資料の印刷をお願いします。
  noun-based request

• この資料を印刷してください。
  verb-based request

But mixing them like:

• この資料を印刷をお願いします

does not work, because it combines the object marking of the verb pattern with the noun pattern in an incorrect way.

Yes, it is polite and fairly formal, especially for everyday workplace Japanese.

It is suitable for:

• office situations
• asking a coworker politely
• asking staff for help
• customer-service situations

A more casual version might be something like:

• この資料、印刷お願いします。

That is common in conversation, but the full sentence この資料の印刷をお願いします。 sounds more careful and complete.
