Other options:
On some computers, you can create a PDF. Open the file, and print it. But instead of sending the document to your printer, you can change the Destination of the file by selecting "Create PDF" or "Save as PDF" as the Destination. Save to your computer and attach to the webpage or email message.

Or, you can print the document and take it to FedEx Office, Staples, etc. They can scan it for you and save it to a "thumb drive" that you bring with you or purchase there. This option will cost a little money, but it'll get the job done.
