印刷 is a suru-noun. That means it can work:
In this sentence, it is being used as a noun because the pattern is:
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:
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:
Then をお願いします attaches to that whole noun phrase.
So the structure is:
If you used a verb instead, then 資料 would take を:
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:
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.
So if you mean print this file/document, 印刷 is appropriate.
If you mean make photocopies of this paper, Japanese speakers may prefer:
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:
That is normal in Japanese. In context, it is understood that:
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:
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:
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:
A more casual version might be something like:
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.
