Disable ink level indicator on HP psc1205...?

Hi there,

Does anyone know how to do this? I've been using kits to refill the
cartridges (56 and 57) with excellent results, but now the computer
continuously tells me the cartridges are nearly empty - it's getting
annoying!

I've read posts for other types of HP printer that say there's a
hidden option in the "printer assistant", but this doesn't seem to
exist for the psc1205 - not in Windows XP anyway.

Any suggestions gratefully accepted.
