OK, here is the output of /usr/libexec/cups/backend/hp (I don't have
a /usr/lib/cups/backend/hp)
# /usr/libexec/cups/backend/hp
direct hp:/no_device_found "Unknown" "hp no_device_found"
This is the same whether I modify models.dat or not. Somewhat unsuprising
since the psc 1310 series doesn't use the hp backend. I thought the problem
was pretty clear from the description below. hpaio is not working like
hp-setup or hp-toolbox with respect to how they take the info from the
printer (ATTRS{product}=="psc 1310 series ") and use it to read the
models.dat file. hp-setup and hp-toolbox do it correctly, hpaio does not.
