-AVRDUDE will accept 3 Windows parallel port names: lpt1, lpt2, or
-lpt3.  Each of these names corresponds to a fixed parallel port base

-On your desktop PC, lpt1 will be the most common choice. If you are
-using a laptop, you might have to use lpt3 instead of lpt1. Select the
-name of the port the corresponds to the base address of the parallel
-port that you want.

-If the parallel port can be accessed through a different
-address, this address can be specified directly, using the common C
