Printer Command Not Recognized S’abonner

I am trying to print a label but when I do I get a message on my printer that says "Printer command not recognized."  The template I design was working fine till I added a word processor box and then that message started appearing.  When I take it off it works fine again.  I tried adding an image instead of using the word-processor box but I get the same message.  I have tried from the bottom up to build the template and the same thing happens.  What about adding a word-processor box or an image causes this to happen.  I am using BarTender 10.1 and I am using a Tharo H-436 printer.  Any help will be greatly appreciated.  Thank you.
