Your Post Office will usually have a public photocopier, many off them are also scanners so you can scan documents onto a memory stick.
It cost money of course, but so does copying/scanning at libraries.
I got a Cannon printer/scanner/copier for a fiver at the local AgeUK shop, I've never put ink in it to print, but a scanner for a fiver isn't bad.
You can even get a new one for around £45 if your budget will stretch to that. (It's the ink cartridges that cost the money).
