The epkowa backend works fine without the non-free, binary-only plugins
for a large number of devices.  Selected models are only supported with
the aid of a non-free, binary-only plugin.  When this is the case, that
is mentioned in the notes on the supported devices.

The PM-A820 is a model for the Japanese market.  Check the Japanese
download page[1].  FWIW, this model does not depend on a non-free,
binary-only plugin.

We do try to keep the list of supported models up-to-date on the SANE
project pages.  Our list[2] is probably the most complete, one-stop
location for information on all the devices supported by the epkowa backend.
