    Eep! I'm not up to this yet.

    parport0: PC-style at 0xa000 [SPP,PS2,EPP]
    parport_probe: succeeded
    parport0: Unspecified, EPSON S
    parport0: PC-style at 0xa400 [SPP,PS2,EPP]
    parport_probe: failed
    parport0: no IEEE-1284 device present.

    Great! That got the printer working. I've not tested the scanner yet.
    I'm getting the hang of this now.

    I've found and read the parport.txt document and so I edited
    conf.modules to add the line:

    options parport_pc io=0x378,0xa400,0xa000 irq=7,auto,auto

    And I'm up and running!
