reallpt (direct parallel port passthrough),

file (records data to a file or passes it to a device),

printer (virtual dot-matrix printer, see [printer] section)

Additional parameters must be in the same line in the form of parameter:value.

for reallpt:
 - Windows:
    realbase (the base address of
                   your real parallel port).
    Default: 378
    ecpbase (base address of the
                   ECP registers, optional).
 - Linux:
    realport (the parallel port device
                 i.e. /dev/parport0).
 - for file: 
    dev:<devname> (i.e. dev:lpt1) to forward data
           to a device, or append:<file> appends
           data to the specified file.
           Without the above parameters data is
           written to files in the capture dir.
           Additional parameters:
             timeout:<milliseconds> =  how long to
              wait before closing the file on inactivity
              (default:500), addFF to add a formfeed
              when closing, addLF to add a linefeed
              if the app doesn't, 
              cp:<codepage number> to perform
              codepage translation,
              i.e. cp:437
 - for printer:
     printer still has it's own configuration
