Dell c2660 Won't Print Emoji

It started a few months ago.  My fifth-grade daughter had created a document and when I went to print via google cloud, I got a Data Validation error.  Print job report showed the document had printed and the error report did not include the 016-720 error.

I connected directly to the printer via USB and still the problem persisted.  Her account is through school and is very tightly locked down.  I figured a setting somewhere was interfering and gave up.

Last night i tried to print a google doc via google cloud printing and got the same error.  I rebooted the computer.  I rebooted the printer.  I reset the printer defaults and rebooted again.  I cleared the job and error history and rebooted again.

I connected directly to the printer via usb and tried again.  This time I got an error page followed by the document I submitted up to where I had included emojis in the text.  I deleted the three emojis and resubmitted.  This time I got the same error page followed by the submitted document up to where I had included more emojis.  I deleted the second batch of three emojis and the document printed successfully.

What do I need to do to allow the printer to handle the complete unicode library?  I have a Chromebook and a printer and so any Windows/iOS requirements are problematic.
