You can find great details about PC parallel port / printer programming on parallel port in lvr parallel port page http://www.lvr.com/parport.htm
If it is standard printer all pins
1) 8 data pins (output to micro)
2) 5 staus pins (input to micro)
3) 4 control pins (output to micro)
will be connected to the I/O port pins of the micro. Then it is similar to dos printer programming.
the more details of how to control data flow is given in beyond logic parallelport page for standard/ecp/epp methods http://www.beyondlogic.org/index.html.
Cheers
