Digital BW, The Print

I have an epson 1280 set up for B&W with Piezo plug in through PS7. 
everything had been working fine with great prints until yesturday 
when I went to print, the print head would pass over the paper a few 
times, giving me about .66 of inch of dots then eject the paper. 
This was using the Piezo Plug in.  I took the same image printed 
from PS and it printed fine albeit ugly results without the plug in. 
I have tried reinstalling the piezo-plug in -no help.  Any 
suggestions. Help
