Canon printer creates two devices on router

When I turn on my wireless printer, I get two devices showing up in my connected devices list.  One correctly displays the name of the printer and one just has a generic device name starting with DEV- and followed by 3 pairs of alpha numeric characters separated by colons.  (Ex: DEV-73:3D:F5).  The unknown device shows up as being wired.  My Canon wireless printer is not connected using a wired connection, it is only wireless. Can anyone explain what the unknown device is?
