UPDATE (5/2/2015):  After getting a response from someone about what I might be doing wrong, I looked deeper into the issue.  It turns out there is a list of compatible printer that  this device supports.  You should check if your printer is on that list or make sure your printer uses PCL or PS.  Thanks to @Holcomb (see comment below) for clarifying this. If it is not compatible with these standards, don't bother going through the headache of buying and trying to configure. It will not work. Go to www.tp-link.com/Resources/document/TL-PS110P_Compatibility_List_2.pdf to find the list of compatible printers.
