If you've ever needed to print something out while on the road, or needed to meet a deadline when no printer was in sight, or took your USB thumbdrive to work to print out your resume so you could apply for another job, Net Print is for you.
It's easy to use, but you'll have to fumble around a bit if you aren't used to reading Japanese:
1) Make an Account
To start out, you'll have to make an account at the Net Print website. Click on the big pink button that says ユーザー登録(ゆーざーとうろく). After agreeing with the license terms by clicking 同意する(どういする) and the privacy terms by clicking 承諾します(しょうだくします).
On the following page, fill in your name (氏名), kana for your name (ふりがな), telephone number (電話番号), and e-mail address (メールアドレス). You'll enter the e-mail address again to confirm (確認入力), choose a login ID (ユーザーID). The final two options are a survey (アンケート) and an opportunity to sign up for the Net Print e-mail magazine (メール配信).
The survey asks "how you heard about this site" and you must choose one option. The final option, その他, is fine, unless you want to assert that you heard about it from our nameless website with その他インターネットサイト. The default selection on the e-mail magazine is set to not subscribe (希望しない).
Click the bottom button, 登録する, to complete your application! You should receive an e-mail at the account you used to sign up. Click on the link in the e-mail to activate your account and sign in for the first time.
2) Upload a Document
When you log into your account, you'll be greeted with this screen:

You can select files up to 2 MB in size from the following formats:
Word (doc, docx, rtf), Excel (xls, xlsx), PowerPoint (ppt, pptx), image files (jpg, png, tif), Microsoft XPS files, and Adobe PDFs.
You'll also need to set the paper size and color settings. The upload will generate a reservation number, which you'll type into the copy machine at 7-11 to retrieve your document from the Internet. You can set a password (4 digits) so that others can't see or print your documents without it. You can have an e-mail sent to your computer, cell phone, etc. that shows the name of the document and its reservation number. (See the above image for details.)
When you've uploaded the window, it will appear on your home screen along with its reservation number:

3) Go to a 7-11 and Print!
Uploaded documents will stay on the server for one week. You can print it out at the multicopy machine in any 7-11 in Japan. From the main menu on the copier, select "Net Print" and then type in your reservation number. Black and white prints cost 20 yen (on B5, A4, B4, and A3 size paper), and from 60 to 100 yen per sheet for color prints, depending on paper size.
