    ! HB_ISPRINTER(), ISPRINTER() fix to open the port name with CREATE
      flag (= CREATE_ALWAYS on Windows). It may fix port detection in
      certain situations. Tested on Windows 7 x86 and x64, whereas it
      will now return .T. if the port is associated with a queue,
      and .F. if it isn't. It seems to cause no harm on OS X. Please
      test it on other systems and other LPT scenarios (f.e. with real
      hardware device attached).
