Printing Things in Tokyo

I need to get an email printed, but as I'm only in Tokyo for a short time, I don't have access to a printer. Is there somewhere that I can go to easily print things? I have a net print account with 7-11, but it seems as though I can only upload images. Is there somewhere I can go to print directly from my email account or maybe even a USB flashdrive? Thanks!

A lot of kinko's in Central tokyo.
I can't find English infomation though.

You can rent PC and print out.

Great, thank you very much.

You can upload pdf files.

You can do that at 7-11, and probably any other convenience store with a copy machine.

Thanks, that's really helpful :)

If all else fails, use the 'Print Screen' [PrtSc] button, which copies an image of the screen to your clipboard, paste it into any imaging software, crop the bit you want and save it as a .jpg file. It's not ideal, but it will work. Using webmail, reducing the screen magnification (a browser function-a slider, bottom right in Opera, other browsers should have something similar) will allow more on to the screen before you hit PrtSc.
