Many different remote printer names may be set up, all directed
to the same Ethernet remote host, and each is given a different
local printer name to be redirected. Different types of print jobs

using different filters.
The remote printer name options used to invoke the different

All other remote printer name options will be treated the same as
lpb.

with a form feed appended:
% lpr -plpaf txtfile
