It means that he does not know what your problem is. Since mankind invented
the PC, the printer ports have been on the same addresses, whether on the
ISA or PCI bus. The exact addresses can be found in memory at location 0:408
for lpt1:, 0:40a for lpt2: and 0:40c for lpt3: What more do you need to
know??

The exact meaning of the addresses (data, status and control) can be found
anywhere on the net.
