Hi Gordon,
I think the problem might be the print driver settings.
Please start AudioLabel and open the Print Dialog. Make sure the 
HP Color Laser Jet 4650 PCL 5c printer is selected, and then click the 
Printer Properties  button. From there, click the 
Print Driver Properties button, which opens the HP 4650 print driver.
There is a print driver option called 
Graphics Mode that should be set to 
Send Graphics As Raster (as show below).

After changing this option and pressing the 
OK button, please try printing again.
Please let us know how it goes.
