That was 11 hours ago, so he has probably had loads of answers by now. If not, here is how I would do it...
- Go to Open Street Map.
- Zoom and slide the slippy map to the area you need.
- Hit the "Export" tab.
- Choose the format you want (it's probably going to be Mapnik for a document, or embeddable HTML for a web page).
- Choose the option you want (its probably going to be PNG or JPEG to embed in a a document. If you don't know which of these you want then it probably doesn't matter, so use the default. Use PDF if you want to email something that people can easily print).
- Hit the Export button.
