The printer in staples/fedex/local print shop down the road. Unless you print a lot (like business/university department amounts), or have some high levels of paranoia about your documents, you're way better off letting someone else deal with the capital costs of the printers.

Check your library too. Mine has cheaper printing than Staples and a free allowance.

The whole point of having a printer is not having to waste time driving somewhere to print something.

Not to mention the extortionate fees such places charge because they prey on the elderly and technically illiterate. One of the majors(can't recall if Staples, Kinkos etc.) recently tried to charge my parents $2/page to fax some records to a new doctor which would have been >$100.
