hmm,
ok, then last try using other method:
switch OFF ur printer completely.
go to Printers folder and remove any listed there.
you'll find a link telling, ADD PRINTER
click it, choose the option of you have the driver disk, and click browse and select that folder that you unzipped (the one u downloaded from my server)
and it will recognize it as printer 670c and will show up in list,
just click OK OK and end the mess up
restart the system and see if the driver is working.
