Printing with EPSON C80 stopped working

Running a debian sarge configuration - I have a epsom stylus c80 colour 
printer connected to the parallel port.

Until recently this printer has been working perfectly under cups - but 
recently a test page showed missing cyan ink.  I assume some ink cartridge is 
low - especially as the light on the printer that says this is on.

I have replaced the cartridge but

a) The light is still on, and
b) Cups attempt to print a test page does nothing

I installed the escputil package to try and see whether that could provide any 
information but when I run

escputil -i -r /dev/lp0 

from the command line nothing happens (I get a short message about using 
escputil -l to get more help but then it hangs without completing forever).

I've tried this with cupsd running and with cupsd halted.

Also 

echo -en "blah\f\r" > /dev/lp0

when cupsd is running comes back saying device or resource busy - when it is 
not running this command hangs too.

I am at a loss of what to try next - any ideas
