Is there an Apple device to help print wirelessly from a wired printer?

Apple doesn't, but the printer manufacturer might. It will really depend on the make & model of your printer.

Most newer printers are AirPrint capable ... or have something equivalent, like HP's HP Print. However, this would mean that the printer must support wireless printing natively. Neither of these technologies would make a non-wireless printer wireless.

One option is to get a small network device, known as a wireless print server, that you would connect to the printer's Ethernet port that would provide it with wireless connectivity to your local Wi-Fi network.

If you are familiar with the Raspberry Pi, you can also use one of these as a wireless print server.

Finally, if by "wired" you mean USB, and not Ethernet, then there are wireless print servers for both types of connections.

Some examples are:
