/* 
   Mythical replies from 5700l that needs to be dealt with 
   for USB printing on 5700L to work.
   5800L, 5900L, 6100L, 6200L can print even if we don't read
   back the reply. Anyway, we do because there are some
   advantages (smart flow control and status feedback are
   possible).

   The reply size seems to be simply related to the first
   byte of a 2-byte command. The caller passes the value
   through "code".

   -1 should never occur.
   0 just means no reply is expected.
