Does the Walmart supercenter on watt Ave have a copy machine that I can use to print out documents?

You can print photos so possibly can print documents.

No Walmart does not have a copy machine you can use the best place would be a public library or staples

It's pretty hit or miss. You never know whether they are out of everything or have a decent selection.r

Yes it does, if you go to the photo/camera section you should find what you need there.
